Product benefits

"Relying on champions to co-create tomorrow's foot comfort solutions that are even more efficient and innovative." That's the challenge of offering you the best in running socks! That's why the Run Ultra running sock was developed with both our expertise in the foot domain, and the field feedback from our athletes and the Sidas-Matryx Team.

The sock acts like an exoskeleton around your foot to stabilise it, provide support and compensate for muscle fatigue.

The Run Ultra socks have two grip strips so that they never slip in the shoes. The toe box is also wider to allow greater freedom of movement to the toes and prevent them from rubbing against each other. The socks also have strapping on the metatarsal heads and heel areas.

Break your limits with the Run Ultra socks!

CAUTION: The socks are very tight fitting. If you feel uncomfortable in such socks, we advise you to take the size above yours.
