The big toe plays a crucial role in running when it comes to balance, stability, and efficient propulsion.

That's why T-Free® technology was developed in collaboration with top athletes such as Jonathan Albon. It gives the big toe more freedom of movement so that it can unfold independently—for noticeably more comfort, better alignment, and increased stability, especially when running on roads.

Details:
• “In & Out” construction: increased comfort without cut threads
• Separation for the big toe: frees the big toe to restore comfort and stability
• Ankle support: support strap for a secure and stable fit
• Protective zones: in the ankle, toe cap, and heel areas
• Breathable & airy mesh fabric
• Wide grip strip: improves adhesion between the sock and the sole
• Odor management: Polygiene StayFresh™ technology
• Reflective band

Fabrics:
53% polyamide, 32% polyamide multifilament, 9% silicone, 5% elastane, 1% reflective threads
