The Nike combat-sports footwear range — HyperKO, HyperKO 2, HyperKO 2 SE, Machomai 2, Machomai 3, Speedsweep, Tawa, Fury, Hypersweep and Inflict — is built on a deliberately narrow last for ring agility and pivot grip. That narrow profile, combined with Nike's tendency to run half a size short of the marked UK size, is why our customers consistently fit better when they order half a size up from their usual everyday shoe.
Fit tip: Order half a size up from your normal size. This is Athlete Performance Solutions' official Fit Tip (Nike's authorised combat-sports licensee) and it matches the feedback we hear from M4F customers. If you have wider feet or you plan to wear a thicker training sock, consider a full size up.
The UK and US Men's sizes shown on each Nike product page follow the conversion in the table below. US Women's sizing runs 1.5 sizes higher than US Men's for the same shoe (i.e. a Men's US 8 is a Women's US 9.5).

Nike Machomai 3 SE Boxing Boots 900 Multicolour
Statement-piece styling meets proven performance in the Nike Machomai 3 SE Boxing Boots in 900 Multicolour — the special-edition release of Nike's flagship boxing boot. The Machomai 3 SE keeps the speed-first build that made the line famous on the amateur and pro circuit but pairs it with a louder, photo-ready colourway designed for fighters who want their kit to read on camera.
The Machomai 3 platform replaces the discontinued 2 with a more breathable mesh upper, redesigned eyelets and a more durable gum-rubber outsole — keeping the light feel that made the line famous while extending its life on the canvas. The 900 Multicolour edition takes that platform and dresses it for ring lights, cornering and showcase fights. Whether you're stepping into the ring as the headliner or running drills in your usual gym, the SE delivers the same Machomai feel with extra visual punch.
Main features:
- Upgraded mesh upper for added breathability, comfort and durability
- Nimble, flexible gum-rubber outsole for maximum traction and ring control
- Redesigned eyelets remove foot pressure and deliver a cleaner aesthetic
- Lightweight upper materials minimise moisture absorption through hard rounds
- Special-edition Multicolour styling built to stand out under ring lights
- Available in nine sizes from UK 7 to UK 11
