Two pairs that look alike on the shelf can hide two very different outsoles: studs moulded into the sole, or studs that unscrew one by one. The gap is easy to miss when buying, yet it decides which pitch the pair was designed for, how much upkeep it needs and, above all, what your rulebook allows. Here is what the manufacturers and the official texts say, and nothing more.

The 2-minute summary
- Two constructions: Under Armour defines moulded cleats as having "fixed studs built into the outsole", and detachable ones as letting you "change the studs to match the field, weather, or way you play".
- The rulebooks disagree: the 2026 IFAF international text only caps stud length at half an inch, while the 2026 German rulebook bans detachable studs outright.
- Surface: Under Armour points natural grass towards moulded studs, and players who switch surfaces towards detachable ones.
- Position: detachable studs are given as preferable on the offensive and defensive lines, moulded ones for the speed positions.
- Upkeep: on a detachable pair every stud comes off and is cleaned separately, which a moulded outsole spares you.
- European supply: our catalogue holds one detachable model against five moulded ones, and the best-stocked specialist retailer lists only three.
One-piece outsole, or studs that unscrew
The difference is purely mechanical. On a moulded pair, the studs and the outsole come out of the same mould and nothing can be taken apart. Under Armour describes them as having "fixed studs built into the outsole for a consistent feel and easy upkeep". On a detachable pair, each stud screws into a threaded socket set into the sole, and Under Armour sums up the point in one line: they "let you change the studs to match the field, weather, or way you play".
That is the only difference in principle between the two families. Everything else, upper, plate, cushioning, size, is chosen the same way: our guide on how to choose football cleats covers those points, and cleat fit is measured identically either way. The catalogue keeps the two apart, with moulded cleats on one side and detachable cleats on the other, inside the wider football cleats collection.
What the rulebooks say, and where they part ways
This is the point most buying guides skip, and there is no single answer to it. Two official 2026 texts treat detachable studs differently.
The IFAF international rulebook, Football Rules and Interpretations 2026 edition, lists under rule 1-4-7-d, among illegal equipment, "cleats that extend more than ½ inch from the base of the shoe", that is 12.7 mm, and refers to its Appendix E for the full specifications. It does not ban removable studs: it only talks about length.
The 2026 German rulebook, published by the referees' organisation AFSVD for the AFVD, is stricter. Its article 1.4.7 d lists "removable shoe studs" as illegal equipment, and article 1.4.7 e adds that non-removable studs longer than 13 mm from the tip of the stud to the sole are illegal too. In other words, a detachable pair that fully complies with the international text does not comply with the German one.
We are not picking a winner: both are official, and your federation decides. Before buying a detachable pair, check the rulebook used in your league. Worth noting in both texts: shoes are not on the list of mandatory equipment (rule 1-4-3 for IFAF, 1.4.3 for the German text), unlike the helmet, shoulder pads, mouthpiece or knee and thigh guards.
Flag football follows its own rulebook: see our guide to flag football cleats.
Which surface each outsole is sold for
Under Armour ties the two constructions to surfaces explicitly. Players on natural grass "usually choose molded cleats with permanently attached studs", while anyone expecting both surface types should "consider a pair of cleats with detachable studs that allow you to change between soft studs and hard spikes based on the surface you're playing on". For synthetic turf the brand points to turf shoes with small nubs rather than conventional spikes.
Bridge Sports, the European retailer with the deepest detachable range, says much the same in its category text: these shoes are "made to be used on heavy grass pitches", synthetic turf remains possible if the surface is not too compacted, and it advises against hard ground, citing ankle risk. That is a retailer's recommendation rather than a rule, but it lines up with the manufacturer's.
What it changes by position
Under Armour's position guide is the only manufacturer table we could open on the subject. It gives detachable studs as preferable on the offensive line and the defensive line, with a high or mid cut, which is where traction demand on short steps is highest. For quarterback, tight end and linebacker the brand leaves the choice open between moulded and detachable. For the speed positions, including wide receiver, running back and kicker, it lists moulded studs only.
That table is still a manufacturer's view, not an obligation: no rulebook ties an outsole type to a position.
Upkeep: the day-to-day gap
On a moulded pair there is nothing to take apart, which Under Armour sums up as "easy upkeep". On a detachable pair the same brand advises you to "remove each stud or spike and clean it individually": maintenance happens piece by piece, and the threaded sockets need cleaning too. That is the price of modularity, and it is the most concrete thing to weigh before buying, because a worn or broken stud can be replaced on a detachable pair, whereas a worn moulded outsole goes out with the shoe.
What Europe actually sells
Supply almost settles the question on its own. Our collection holds nine moulded models against a single detachable one.

On the retail side, the Bridge Sports detachable aisle listed three pairs on 22 October 2026: the New Balance MF993MK at €90.00, the Nike Super Speed D at €60.00 and the Under Armour Hammer Mid at €139.00, the last one shown as a final pair in EU 42.5. No manufacturer page could be opened for any of the three, which is why the Hammer Mid listing is still flagged as unconfirmed on the site: we do not publish specifications the manufacturer does not publish.
FAQ
Are detachable cleats banned in American football?
It depends on the rulebook in force. The 2026 IFAF international text does not ban them and only caps stud length at half an inch from the base of the shoe. The 2026 German rulebook bans them explicitly. Ask your own federation.
How long is a legal stud?
IFAF sets the limit at half an inch, 12.7 mm, measured from the base of the shoe. The German rulebook uses 13 mm, measured from the tip of the stud to the sole, and only for non-removable studs.
Can football cleats be worn on synthetic turf?
Under Armour points synthetic surfaces towards turf shoes with small nubs. Bridge Sports considers a detachable pair still workable on synthetic turf if the surface is not too compacted, and advises against hard ground.
Do beginners need detachable studs?
Nothing in the official sources requires it, and European supply pushes the other way: five moulded models out of six in our collection, and a detachable aisle down to three pairs at the best-stocked specialist retailer.
