Sigma Runner Moonlit Black - Lightweight Running Shoes for Men & Women - Perfect for Jogging, Gym Workouts & Outdoor Activities

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

• 249g / 8.8oz (Size US 9M)

The result? Less fatigue, more flow, no matter your cadence or distance.
