Shin Guard Types and Sizing Guide

Shin guards are the piece of equipment players think about least and complain about most. They ride up, they slide sideways, they get shoved down to the ankle by half time, and by U14 half the squad is wearing the smallest pair they can get away with.

Almost all of that is a sizing and type problem rather than a comfort problem. The tibia is the most commonly fractured bone in the sport, and it sits directly under the skin with nothing to absorb an impact, which is why the guard exists in the first place. Here is how to pick shin guards that a player will actually keep on.

Slip-in

A plate and nothing else. It goes under the sock and is held in place by the sock, a sleeve, or tape.

This is what most older and higher-level players wear, for one reason: minimal bulk. Nothing sits around the ankle, nothing restricts movement, and the guard disappears once it is on. The trade is that it will move if it is not secured, and securing it properly is a step players skip.

Ankle guards

A plate with padded ankle wings on either side and a stirrup that runs under the foot to hold everything in position.

The stirrup is the underrated part. It stops the guard from riding up, which is the single most common complaint from parents about young players. The ankle padding adds protection where kicks land often in youth soccer, particularly in age groups where tackling technique is still developing.

This is the default recommendation for younger players, and it is a reasonable one for defenders at any age. Some players find the ankle wings restrictive, which is a legitimate reason to move away from them once they are old enough to secure a slip-in properly.

Sleeve guards

A compression sleeve with a pocket or a bonded plate, pulled on like a sock.

These solve the retention problem without tape. The sleeve holds the plate against the leg, so it stays where you put it. They are also the easiest for a young player to put on unaided, which matters more than it sounds when a coach is trying to get eleven players ready.

The catch is that they run to a size. A compression sleeve that has been stretched out over a season stops holding the plate, and one that is too tight is uncomfortable in heat.

Shin guards are sized by player height, not by shoe size or age. Age charts are a proxy, and they fail on anyone tall or small for their year.

Treat this as a starting point. Sizing varies between manufacturers, and the only reliable check is the fit test below.

The fit test

• The guard should sit roughly two inches below the bottom of the kneecap when the player is standing.
• The bottom should end just above the ankle bone, or cover it if it is an ankle guard.
• It should cover the width of the shin, not just the centre strip. A guard narrower than the bone leaves the edges exposed.
• The player should be able to bend the knee fully and squat without the top of the guard digging in.
• It should not move when the player jogs on the spot.

Why most players wear them too small

Because small guards are more comfortable and less noticeable, and because nobody checks after the first fitting. A guard that is too short leaves the lower shin exposed, which is exactly where a mistimed tackle lands. A guard that is too narrow leaves the sides of the bone unprotected. Both feel fine right up until the moment they do not. If a player has grown since last season, the guards need checking along with everything else.

Shin guards are mandatory under the Laws of the Game, and referees can and do check them. Beyond that, requirements vary. Some youth leagues and state associations specify that guards must carry a safety standard marking, and some competitions require they be fully covered by the sock. Both are worth confirming with your own league before the season rather than at the first match.

The practical version: buy guards that carry a recognised safety marking, make sure the socks cover them completely, and you will not have a conversation with a referee about it.

Keepers wear shin guards too, and the requirement applies to them the same as anyone else. Most prefer slip-ins, because ankle wings interfere with diving and getting up quickly.

Worth noting that a keeper takes contact in different places to a field player, and shin protection is the least of their equipment decisions. Goalkeeper glove cuts and sizing cover the piece of kit that actually determines how they play.

How the guard is held on matters as much as which guard it is, and this is where slip-ins fail.

A properly fitted match sock will hold a slip-in guard reasonably well on its own. A stretched-out sock will not, and neither will a sock a size too big. If a player’s guards keep sliding, check the socks before you replace the guards, because that is the cause more often than not. Replacement soccer apparel is a cheaper fix than new guards.

Beyond that, there are two options. Sleeves, which are the tidier solution and reusable. Or tape, wrapped over the sock above and below the guard, which is what most professionals use and what most youth players copy without being taught to do it properly. Tape should be snug, not tight enough to restrict circulation, and it should come off after the match rather than being left on through a car ride home.

Guards trap heat and sweat against the leg for ninety minutes, and in August in Texas that means they come off soaked every session.

Left in a kit bag, they develop odour and bacteria fast, and skin irritation from dirty guards is common enough in youth soccer to be worth heading off. Wipe the plates down after every session, let them air dry fully rather than sealing them in a bag, and wash sleeves and socks after each use.

Guards with foam backing hold moisture more than bare plastic ones. If a player is training five days a week through a Texas summer, two pairs alternating will last longer and smell considerably better than one pair used daily.

Same rule as everything else in the bag: fit the player you have now.

An oversized guard rides up into the knee when the player runs, which is uncomfortable enough that they will pull it down mid-match or push it into the sock in a way that leaves the shin exposed. Guards are among the cheapest items in soccer, so there is no meaningful saving in buying big and none of the fit trade-offs are worth it. Check the height chart at the start of each season alongside soccer cleat types and the rest of the kit.

If a player has been complaining about their guards all season, it is almost always the size or the type rather than the guard itself. Bring them into any of our five Texas stores in San Antonio, San Marcos, Tomball and Katy and we will get the height right and put them in a type they will actually keep on.

What size shin guards do I need?

Size by height rather than age. As a guide, a guard should sit about two inches below the kneecap and end just above the ankle bone. Check the height chart above as a starting point, then confirm with the fit test.

Do shin guards need ankle protection?

Not required, but recommended for younger players and useful for defenders. Ankle guards include a stirrup that stops the guard riding up, which solves the most common complaint. Older players usually move to slip-ins for freedom of movement.

Should shin guards go under or over socks?

Under, and fully covered. That is standard under the Laws of the Game and many leagues check it.

How do I stop shin guards from sliding down?

Check the socks first, since stretched or oversized socks are the usual cause. If the socks are fine, use a sleeve or tape above and below the guard. Ankle guards with stirrups solve it structurally.

How often should shin guards be replaced?

When the player outgrows them, when the plate cracks, or when the foam backing compresses and stops rebounding. Check the fit at the start of every season for any player who is still growing.
