Mizuno Wave Rebellion Flash ($160)

Introduction
The Wave Rebellion Flash is an uptempo trainer/racer featuring a dual density midsole with underfoot Mizuno Enerzy Lite, the same super foam found in the wild Wave Rebellion Pro racer (RTR Review). Below Enerzt Lite we have a firmer white Mizuno Enerzy foam heel wedge.

Embedded in between the two midsole foam layers is a rear to midfoot glass fiber reinforced Wave plate said by Mizuno to be highly rigid and 1141% snappier than pebax plates.
The outsole is an unusual PU resin that is softer than the firm PU outsole of the predecessor Wave Rebellion. On the surface a really good thing as the Wave Rebellion’s was clearly firm plastic and noisy.

The upper is a soft breathable air mesh of a single density with a few rear overlays, a toe bumper stiffener and a semi rigid heel counter with just a rear stiffener.
Pros:
Effective easy to find front propulsion with a snappy toe off Sam/Zack/Renee/Sally/Jana/Adam

Roomy buttery soft single layer mesh upper: : Sam/Zack/Sally/Shannon/Jana
Upper is durable and lightweight: Zack/Derek/Sally/Shannon/Jana
Versatile: tempo runs to shorter races: Sam/Zack/Derek/Sally/Jana

New softer PU resin outsole delivers a dramatic improvement in ride feel over prior much firmer and noisier Wave Rebellion outsole: Sam/Zack/Renee
Non harsh/overly rigid in feel Wave plate geometry back to front: Sam/Zack
Roomier overall fit and feel when compared to other Mizuno models past: Shannon
Cons:
While 8mm drop is appreciated, and at 35mm the heel has plenty of cushion, the 27mm forefoot may get tiring at races over 10-15K for many: Sam/Zack/Derek/Renee/Sally/Adam
Upper may not be secure enough at midfoot for low volume feet at true to size, could use more medial underlays and maybe a gusset tongue: Sam/Renee
Forefoot too flexible for speed work: Derek
