The Wave Shadow is the replacement for the Sayonara series. While the Sayonara merged two previously well-loved shoes (the Precision and the Elixir, both longtime successes), the Shadow replaces a good shoe that never got the love it deserved.
The upper is a mini- mesh with a stitched saddle that offers great midfoot support and a few welded overlays provide a little extra structure in strategic areas. The midsole may be the Shadow’s secret weapon: It has a deceptively flexible and bouncy U4ic foam, that holds up well to high-mileage training. The outersole features a durable rubber compound that has a little extra cush to it. A textured pattern within the tread affords great grip, with the added benefit of being durable enough for everything we threw at the shoe. The Wave Shadow’s performance, durability, and ride earned it our award as the Best Training Shoe.
Testers: "Roomy and airy over the toes, snug heel but without a lot of structure. Great for tempos and big miles. Ran some longer races with good results."
