The days of compromising speed for stability are over. The Motion V combines the best of both worlds. The Motion V features Newton's EMB (extended medial bridge) platform which offers more functional support for runners with medial side pronation or a flatter arch. The Motion V pairs a lightweight, breathable mesh upper and a new 4-way stretch mesh metatarsal panel making it a comfortable shoe for everyone. This model is ideal for high mileage endurance training and racing. The performance of a Gravity in a stability package....no compromises!
