The problem we engineered against

Your foot is moving inside your shoe

Even a few millimetres of internal slippage bleeds energy on every push-off, destabilises direction changes, and generates the friction behind blisters and black toenails. Standard socks grip the floor, not the insole. The slippage goes unaddressed. The athlete compensates on every step.

Our solution

Dual-Sided Grip. Complete Foot-to-Shoe Unity.

Standard grip socks grip the floor. The UltraGrip V2 grips simultaneously in both directions, premium grip pads on both the inside and outside of the sole lock your foot to the sock and the sock to your insole at the same time. The result is foot-sock-shoe unity that no single-sided grip sock can replicate.

The Injury

Blisters

Blisters form when your foot slides inside your shoe. Each micro-movement creates friction between skin layers, separating them and allowing fluid to collect underneath. On court, lateral cuts, sudden stops, and direction changes create the highest slide forces. Standard socks have no grip on either surface, so your foot moves freely inside the shoe with every step.

The Technology

Dual-Sided Grip Technology

Dual-Sided Grip Technology is designed to reduce the micro-movement that commonly occurs between the foot, sock, and shoe during high-intensity athletic movement. In many court sports, rapid lateral changes in direction create small internal shifts inside the shoe. Over time, this movement can lead to friction, energy loss, reduced stability, and the formation of blisters.
