The Wave Sayonara 3 is everyday fast. Lightweight and responsive, it's the ideal neutral trainer whether you're looking to run fast on race day or get-up-and-go-fast everyday. A newly constructed, highly breathable mesh upper embraces the foot and provides a glove-like fit that blurs the line between runner and shoe. A Parallel Wave inside a soft and springy U4ic midsole keeps this shoe light, fast, and responsive.
