THE INTERSECTION OF MINIMALIST PRINCIPLES AND MAXIMALIST CUSHIONING.
A supertrainer that works with you — every stride, every mile.
Whether you’re building your weekly base, pushing tempo, or lining up on race day, the Sigma Runner™ is designed to work with your natural mechanics to keep your stride dialed so you can run longer and recover faster.
Our new run-specific S2R Last features a perfected, anatomical toe-box that promotes optimal forefoot function.
An ultra-breathable jacquard knit upper is designed to contain and cradle the foot over the midsole with targeted exterior and interior laminations.
The Linear Platform™ outsole offers smart cushioning and a stable ride.
Underfoot, the Sigma’s dual-density midsole blends geometry and materials to help you move efficiently mile after mile.
- S30™ glass-fiber infused Pebax® plate adds propulsion and torsional control
- Spectra Foam™ upper midsole provides stability and drives the integrated plate.
- Nitrogen infused Supercritical EVA base layer cushions every stride without muting ground feel
- Fulcrum™ cantilevered toe spring creates additional stability at lower speeds and a smooth rocker feel at a faster pace.
- Perimeter rails in the upper midsole help center your foot through midstance
- Midsole cutaways reduce weight and slap while increasing flexibility
- 34mm Stack height
- 4mm + 2mm offset supports forward momentum without overcorrecting
