The Saucony Triumph 23 uses a re-imagined outsole that is more flexible, giving you a smoother transition from landing to toe-off for strides that feel effortless. They have also changed the tooling, improving the width through the forefoot by 7mm and midfoot by 1mm, this allows a more comfortable feel as well as additional stability. The engineered mesh upper is softer and lighter and highly breathable. Touch points around the shoe are elevated for a plush sensation on step in.
