The Sonic is a new racer/trainer, trainer/racer from Mizuno which incorporates some new approaches to the wave technology. The upper is a thin semi-open mesh in the forefoot with closed mesh in the heel.
The medial side is supported by fused overlays, there is a thin, rearfoot counter, and an open forefoot. The midsole is a new approach for the brand with a very small laterally positioned second density, shaped like a wave, which lends an extra layer of cushion under the heel and mid-foot. The remainder of the midsole is a firm but forgiving foam, which flexes well and protects nicely. The outersole is a nearly full length rubber, thin in its structure but offering excellent traction, durability, and good flexibility. The result is a durable racer that can double as a speedwork/tempo shoe without missing a beat.
Testers: “Low profile, with just enough cushion. Like them for long races and tempo runs.”
