Technology

Built for ground feel

The BARE-XF PRO removes everything between you and the floor. What's left is intentional.

Zero Drop

0mm heel-to-toe drop. 8.5mm heel, 8.5mm forefoot midsole stack. The foot sits completely flat — heel and forefoot at the same level — the way it was built to load. Every muscle from the arch to the hip activates correctly.

// 0mm drop · flat platform

Splay

NaturalFit™ Wide gives the toes room to spread, splay and grip independently. Stronger intrinsic foot muscles, better balance under the bar, more stable base for every lift — the way barefoot training is supposed to work.

// NaturalFit™ Wide · toe splay

Feel

No midsole foam means no signal dampening between you and the floor. Real proprioceptive feedback that builds better movement patterns and stronger feet over time. At 250g, there's nothing in the way.
