Light Stability. This lightweight, low profile trainer provides a touch of stability for those in-between runners. The Puma Faas 350 is ideal for fast runs, workouts, and races.

Upper: Highly breathable sandwich mesh upper. TPU form stripe for comfort. Padded tongue and heel collar with a textile lining.

Midsole: Faas foam midsole composed of EVA and blown rubber for cushioning and response. Removable OrthoLite® sockliner for maximum fit and comfort.

Outsole: EverRide blown rubber outsole for maximum cushioning. EverTrack high abrasion resistant rubber components for extra durability.

"Low-slung and responsive, the Faas 350 S is a no-frills training shoe capable of pulling double duty for faster-paced workouts and long runs. The foam-rubber midsole is exposed, while only a minimum amount of outsole is used to keep the shoe lightweight and superflexible. One drawback: limited traction. Wear-testers said the 350 S slips on wet surfaces. Faster runners appreciated how the shoe performed. 'The Faas 350 would be among my choices if I were to buy only one shoe for everyday training,' says Ulrich Fluhme, 37, or New York City, who has a 2:33 marathon PR and primarily trains in racing flats. Bottom line: A good first step for those curious about trying minimal footwear. "
