G-Form Pro-S Blade Shin Guards Review: Are They Worth It?

Shin guards are one of those pieces of youth soccer gear that seem simple – until your kid decides they hate wearing them.

We went through traditional guards with ankle straps, slip-in guards, different sleeves and eventually G-Form’s one-piece Pro-S Elite before stumbling across a pair of Pro-S Blades on clearance for $5.

They looked a little strange. They felt almost too small and flexible to offer much protection. But for $5, they were worth a try.

More than two years later, our player has worn G-Form Blades through year-round practices and games, we’ve bought a second pair at full price, and they’ve become the shin guards she reaches for every week.

The first pair cost us $5. The second pair didn’t—and we still bought them.

That’s probably the shortest version of this review.

How We Ended Up With G-Form Blades

Like a lot of youth players, our daughter started with traditional shin guards with ankle protection and Velcro straps. They worked, but she was sensitive to the extra bulk, pressure points and socks bunching around them. Over time, we moved through several lower-profile setups—including an Under Armour sleeve system she really liked, Nike Mercurial guards and even inexpensive Nike J Guards paired with those old Under Armour sleeves.

Eventually we tried the G-Form Pro-S Elite. We liked the low profile and one-piece design, but getting the integrated guard and sleeve over her heel was difficult. She’d naturally pull from the top, and over time small holes developed where the upper band met the fabric. Taking them off after games usually required some help, too.

Then we found a pair of G-Form Pro-S Blades on clearance for $5. The black-and-white graffiti pattern was a little wild, but for five bucks they were worth trying. We paired them with G-Form’s retention sleeves, and the setup immediately solved most of the little annoyances we’d been working around.

The Blades were extremely light and low profile. She could put the sleeves on herself, slide the guards into the pockets, pull up her own socks and—just as importantly—take everything off herself after a game. They were comfortable, simple and didn’t get in her way.

Most importantly, she liked wearing them.

When we later wanted another pair in a more traditional color, we bought the navy-and-gold Blades at full price. The original graffiti pair stayed in the rotation as a backup and practice pair.

The first pair got us to try them. The second pair is what convinced us we actually liked them.

What Our Player Likes About Them

Our daughter’s opinion of the Blades is pretty straightforward: she likes that they’re light, small and flexible. Once they’re in the retention sleeves and under her socks, she doesn’t spend much time thinking about them—which is probably about the best compliment a shin guard can get.

She also genuinely likes the navy-and-gold design. Her biggest complaint has nothing to do with comfort or performance: she wishes they were a little more “normal.” Because the Blades look different from traditional hard-shell guards, she still gets the occasional “whoa, what are those?” when a teammate sees them for the first time.

We also asked what she’d choose if her current pair disappeared tomorrow: another pair of Blades or something different. The answer was basically “I don’t know” and a shrug. So this isn’t a case where the player is passionately loyal to a particular shin guard. She just likes wearing these—and as parents, we’re probably more enthusiastic about the overall setup than she is.

They’re Surprisingly Small — Do They Actually Protect?

The first time you hold a Pro-S Blade, it’s hard not to be skeptical. They’re thin, flexible and surprisingly small compared with a traditional hard-shell shin guard. In your hand, they almost feel like they shouldn’t offer much protection at all.

We were skeptical enough that we put one flat on the kitchen counter and hit it with a fist just to see what would happen. It barely seemed to give at all. The material stayed remarkably firm under impact despite feeling flexible in your hand.

There’s some actual technology behind that. G-Form calls the material SmartFlex, which is designed to remain soft and flexible during normal movement and harden when it’s struck. The Pro-S Blade also meets the NOCSAE standard for soccer shin guards.

G-Form makes additional claims about the Blade being thinner and lighter than competing guards, but we haven’t independently tested those numbers. What we can say is that they are noticeably smaller and lighter than the traditional guards we’ve owned.

More importantly, we now have more than two years of actual use to judge them by. Our daughter plays year-round, generally practicing twice a week with games on weekends, and she has never come off the field complaining that a kick to the shin hurt through these guards. In that time, we’ve never noticed a bruise on her shins, either.

That doesn’t mean a small shin guard provides the same coverage as a larger one, or that any shin guard can prevent every injury. In fact, we’d actually prefer the Blades to be slightly longer for a little more coverage. But in our experience, they’ve provided a really good balance of protection and low bulk without getting in the way when she runs, cuts or strikes the ball.

They feel like less shin guard until something hits them.

The RS-01 Retention Sleeve Is Half the Story

The Pro-S Blade comes with a basic mesh sleeve, so technically the $29.99 guards are a complete setup right out of the package. We tried that sleeve and didn’t care for it. Ours went in the trash.

Instead, we use G-Form’s RS-01 Retention Sleeve, which is sold separately for $19.99. Unlike a basic compression sleeve that simply holds the guard against your leg, the RS-01 has a dedicated pocket that the Blade slides into. The sleeve fabric sits between the guard and the player’s skin, and the pocket keeps the Blade securely positioned.

For our daughter, that combination has worked extremely well. The material is lightweight and breathable, the guard has very little room to move inside the pocket, and we’ve never seen her stop during a practice or game to adjust it.

It also makes getting ready simple: sleeve on, Blade into the pocket, sock over everything. After the game, she can pull down her sock and slide the guard out herself.

The downside is price. A $29.99 pair of Blades becomes a $49.98 setup when you add the RS-01 sleeves. That’s not cheap for youth shin guards, especially when the Blade already includes a sleeve.

But having used both, the Blade + RS-01 is the setup we’d buy.

Fit & Sizing

G-Form sizes the Pro-S Blade using both height and calf circumference, rather than age. That makes sense for youth players, where two kids the same age can have very different builds.

Our daughter started wearing a Small when she was about 4’8″. G-Form lists Small for players up to 4’11”, so she was comfortably within the recommended range at the time.

She’s now about 5’3″ and still wearing those same Small Blades and Small RS-01 sleeves. They stay securely in place and haven’t become uncomfortable, although the sleeves have almost certainly stretched somewhat after more than two years of regular wear and washing.

If we were buying a new pair today, though, we’d buy Medium. At her current height she falls into G-Form’s Medium range, and the larger guard would also address our one minor complaint about wanting a little more vertical shin coverage.

The takeaway: don’t use “the old size still fits” as your sizing method. We’d use G-Form’s current height and calf measurements when buying a new pair.

G-Form Pro-S Blade Size Chart

Size	Maximum Height	Calf Circumference
XS	4’7″	11–13″
S	4’11”	13–14″
M	5’7″	14–15″
L	5’11”	15–16″
XL	6’3″	16–18″

Durability & Washing

After more than two years of regular use, the Blades themselves have held up remarkably well. Both our original graffiti pair and the newer navy-and-gold pair still look close to new, despite being used for year-round practices and games.

Cleaning them is easy. We wash the Blades and RS-01 sleeves with the rest of the practice gear, then let the guards air dry. The Blades dry quickly enough to be ready by the next day, although having two pairs is convenient when practices fall on back-to-back nights. On tournament weekends with multiple games in a day, we simply wait until we’re home to wash everything.

The RS-01 sleeves have held up well, too. We haven’t had holes or frayed seams, although the printed designs are starting to show some wear after repeated trips through the washing machine. That’s cosmetic and hasn’t affected how the sleeves fit or function.

That’s been a noticeable improvement over our older G-Form Pro-S Elite guards. Because the Elite combines the guard and sleeve into one piece, pulling the tight lower opening over the heel put repeated stress near the top of the sleeve. Eventually, small holes developed where the upper band meets the fabric.

With the Blade system, the parts that are most likely to wear out are separate. If a sleeve eventually needs replacing, we don’t have to replace a perfectly good shin guard with it. That’s a small design advantage we didn’t really appreciate until we’d lived with both systems.

What We Like — and What We Don’t

Who Should Buy the G-Form Pro-S Blade?

The Pro-S Blade is a particularly good fit for players who hate bulky shin guards or are sensitive to how their equipment feels. They’re light, low-profile and, paired with the RS-01 sleeve, easy for our daughter to manage entirely on her own.

We’d also recommend them to families who value a setup that’s easy to wash, quick to dry and simple to replace piece-by-piece as things wear out.

If your priority is maximum shin coverage, though, the Blade probably isn’t the G-Form model we’d choose. Its small size is part of the appeal, but it’s also the biggest compromise.

For us, the sweet spot is simple: a player who wants the shin guard to disappear once the game starts.

Alternatives to the G-Form Pro-S Blade

The Pro-S Blade isn’t the only shin guard we’ve used. Before settling on it, we spent time with several other styles, and each makes sense for a slightly different player.

G-Form Pro-S Elite — If You Want More Coverage

The Pro-S Elite was our introduction to G-Form. It has the same appeal of a flexible, low-profile guard, but the protection is integrated directly into the sleeve and provides a little more coverage than the Blade.

We actually prefer the Elite’s coverage. What pushed us toward the Blade was convenience: the Elite was harder for our daughter to pull over her heel, and repeated pulling eventually caused holes near the upper band. If more coverage matters more than the removable-guard design, we’d look at G-Form’s integrated options.

Nike Mercurial — If You Prefer a Traditional Guard

Our Nike Mercurials are still buried in the soccer bag as the backup to the backup. They’re a more conventional hard-shell guard and feel perfectly capable, but we didn’t like the sleeve or cleaning them as much as the G-Form setup.

For a player who simply prefers the feel and appearance of a traditional shin guard, though, the Mercurial is the more familiar option.

Nike J Guard — If You Want Simple and Inexpensive

The Nike J Guards were our low-cost, no-frills option. They’re small, lightweight hard-shell guards without much complexity, and we used ours inside an old pair of sleeves we already liked.

They don’t have the flexible feel or dedicated retention system we like about the Blades, but they’re proof that you don’t need to spend $50 to get a simple shin-guard setup.

Final Verdict: Are the G-Form Pro-S Blades Worth It?

For us, yes—with one important qualifier. We wouldn’t just buy the $29.99 Pro-S Blades. We’d pair them with G-Form’s $19.99 RS-01 Retention Sleeves, which makes our recommended setup about $50.

That’s not inexpensive for youth shin guards. But after more than two years of year-round soccer, the Blades themselves have held up extremely well, our daughter finds them light and comfortable, and the separate guard-and-sleeve design is easier for her to manage than anything we’d used before.

We’d still like a little more vertical coverage, and we’d love more understated sleeve options. But neither has been enough to make us look for something else.

The first pair cost us $5. The second pair didn’t—and we still bought them.

For us, that’s the strongest recommendation we can give.
