Best Indoor Soccer Shoes for Youth (2026): IC vs Turf Explained

Indoor and turf shoes look similar but are not the same thing, and this is the single most common mix-up parents make. Indoor (IC) shoes have a completely flat, non-marking sole built for gym floors and futsal courts. Turf (TF) shoes have a sole covered in small rubber studs, built for artificial turf outdoors — and most gyms won’t allow studded soles on their floors at all. If your child plays futsal, an indoor winter league, or needs shoes for gym class, look for a flat, non-marking sole like the picks below. If they actually play on outdoor artificial turf, you want a turf shoe instead — we’ve included one for that case, and our outdoor cleats buying guide covers firm-ground options for natural grass. Two of the picks below are adidas models — see our adidas youth lineup guide if you want to compare them to adidas’s outdoor cleats.
Our Top Picks
Budget Indoor Pick: PUMA Attacanto II Indoor
A true flat, non-marking indoor sole built for cuts and sprints on a gym or futsal floor, in a lightweight, low-profile, lace-up regular fit sized for roughly ages 8 to 16. The affordable entry into proper indoor shoes — it's the indoor sibling of the PUMA Attacanto cleat, but with a completely different sole.
- Indoor (IC) sole
- Lace-up
- Non-marking
- Ages ~8–16
Best for Futsal: adidas Predator Sala Indoor
Built specifically for the futsal court, with a flat, non-marking rubber outsole designed for polished floors and Predator-line textured grip zones that help with ball control on touch and passing. A floating-tongue lacing system leaves room for growing feet — the performance pick for kids who play real indoor or futsal.
- Indoor/futsal (IC) sole
- Floating-tongue lacing
- Non-marking
- Textured grip upper
Premium Classic: adidas Samba Indoor
The iconic Samba, built with a leather upper and a grippy, flat gum-rubber indoor sole — a 4.7-star shoe with over 1,700 ratings that doubles as a casual everyday shoe off the court. The do-it-all indoor classic for a kid who wants one pair that works for futsal, gym class, and everyday wear.
- Indoor (IC) gum sole
- Leather upper
- Non-marking
- Doubles as casual shoe
If You Need Turf Instead: adidas Goletto IX Laceless Turf
The odd-one-out here on purpose: this is a turf (TF) shoe with a lugged, studded sole — not a flat indoor shoe, and not appropriate for a gym floor. Included for parents whose child actually plays on artificial turf rather than an indoor court. Laceless and runs narrow and small, so size up.
- Turf (TF) studded sole
- Laceless
- Artificial turf only
- Runs narrow — size up
IC vs. TF vs. FG: Picking the Right Sole for Indoor Play
IC (indoor) vs. TF (turf) vs. FG (firm ground)
IC (indoor court) shoes have a flat, non-marking gum-rubber sole built for gym floors and futsal courts — no studs at all. TF (turf) shoes have a sole covered in many small rubber studs, built for artificial turf carpet outdoors. FG (firm ground) cleats have longer molded studs for natural grass. These are three different soles for three different surfaces, and the most common mistake parents make is buying a turf or firm-ground shoe for a kid who actually needs flat indoor shoes — or the reverse.
Why gyms ban studded and marking soles
Polished gym floors and futsal courts are easily scuffed or marked by rubber studs, and many facilities have explicit rules against any shoe with a lugged or studded sole. Beyond the rules, studded soles also don’t grip a smooth indoor floor well — the traction that helps a turf or FG shoe on grass or carpet can actually cause slipping on polished concrete or wood. A non-marking, flat indoor sole is built specifically to grip these surfaces safely without damaging them.
Futsal vs. casual indoor play
If your child plays organized futsal or an indoor winter league, a purpose-built indoor shoe like the Predator Sala above — with grip-focused texturing and lacing designed for growing feet — is worth the investment. For occasional gym class or pickup games, a more casual indoor shoe like the Samba covers both the court and everyday wear, which is often the more practical choice for a family not yet committed to a regular indoor program.
Sizing for growing feet
Indoor shoes fit much like sneakers, so the same sizing logic applies as with outdoor cleats: leave a thumb’s-width of room at the toe and check the fit note for the specific model, since some run true to size and others — like the turf option above — run narrow and small. Re-check fit each season, as feet that have grown can outgrow an indoor shoe just as quickly as a cleat.
Can you wear indoor shoes outside?
Yes — the flat sole works fine on pavement, and shoes like the Samba are popular as everyday casual wear. The trade-off is wear: a sole designed for smooth indoor floors will break down faster on rough outdoor surfaces like asphalt than it would staying on a gym floor. If a pair is doing double duty as an everyday shoe, expect to replace it sooner than if it were used only for indoor sessions.

Frequently Asked Questions
Indoor (IC) shoes have a completely flat, non-marking gum-rubber sole, similar to a sneaker, designed for gym floors, futsal courts, and other hard indoor surfaces. Turf (TF) shoes have a sole covered in dozens of small rubber studs, designed to grip artificial turf carpet outdoors. They look similar from a distance but serve different surfaces — a turf shoe's studs can mark, damage, or simply slip on a gym floor, and an indoor shoe's flat sole won't grip artificial turf the way a child needs for cutting and sprinting.
Most gyms and indoor facilities won't allow it. The small rubber studs on a turf shoe can scuff or mark a polished gym floor, and many programs explicitly ban any studded or lugged sole on indoor courts for this reason. Beyond the rules, turf studs also don't grip a smooth indoor floor well, which can actually be less safe than a proper flat-soled indoor shoe.
For regular futsal play, yes — a dedicated indoor (IC) shoe like the adidas Predator Sala above is built for the quick stops, pivots, and low-bounce ball control that futsal demands, with a sole designed to grip a polished court without marking it. A casual sneaker can work in a pinch for a one-off gym class, but it won't hold up to regular futsal training the way a purpose-built indoor shoe will.
Yes, and many kids do — the Samba above is popular as an everyday casual shoe as well as an indoor court shoe. The flat sole works fine on pavement or hard ground. The catch is durability: a sole designed for smooth indoor floors will wear down noticeably faster on rough outdoor surfaces like asphalt or concrete than it would on a gym floor, so don't expect an indoor shoe to last as long if it's doing double duty as a daily walking shoe.
A non-marking sole is made from a rubber compound that doesn't leave scuff marks or black streaks on indoor floors — the same idea as a non-marking basketball or volleyball shoe. This is the key feature that lets a shoe onto a gym or futsal court in the first place; most facilities check for it, and a studded or marking sole will get a player turned away regardless of how good the shoe otherwise is.
