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 Bytomic 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).

Description
When footwork wins fights, the Nike Machomai 3 Boxing Boots in 400 Blue/White give you the same proven Machomai platform in a fight-night-ready colourway. The Machomai 3 replaces the loved-and-discontinued Machomai 2 with a more breathable mesh upper, redesigned eyelets and a more durable rubber outsole, while keeping the lightweight feel that made the line famous on the competition circuit.
The 400 Blue/White is the brightest of the Machomai 3 colourways — built for fighters who want to be visible under ring lights and stand out in their kit. The mesh upper breathes through long sessions and humid gyms, the gum-rubber outsole keeps you confident on cuts and direction changes, and the redesigned eyelets take pressure off the top of the foot for all-round comfort. Whether you're shadowboxing rounds, hitting pads or going to war on fight night, the Machomai 3 stays out of your way.
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
- Bright Blue/White colourway built for fight-night visibility
- Available in thirteen sizes from UK 6 to UK 11
