INTRODUCTION

The adiZero Boston is a moderate feature, moderate neutral shoe designed for speedwork, racing and daily training. It is built with a semi-curved shape.

CUSHIONING

  • Formotion is a gender specific decoupled heel system designed to dissipate shock from heel strike.
  • adiPRENE+ is utilized in the forefoot and is a resilient EVA based foam intended to provide cushion under the metatarsal region.
MIDSOLE
  • CMEVA is compression molded EVA which is an industry standard midsole material designed to offer durable cushioning.
  • Formotion is a gender specific decoupled heel system designed to dissipate shock from heel strike.
  • Torsion System runs along the bottom of the midfoot and is a wishbone shaped thermoplastic unit that is gender engineered to allow the forefoot and rearfoot to move independently for increased stability.
UPPER
  • Open Mesh is used throughout the upper and provides breathability.
  • Adidas Logo overlays are strategically placed to wrap the upper around the foot.
  • Traditional Sockliner
  • AdiPrene 45 Last is a full length strobel last constructed from Adidas' most soft foam.
OUTSOLE
  • AdiWear is utilized in the lateral heel and is a durable carbon rubber.
  • Blown Rubber is lightweight and offers grip for increased traction.

Comments: Wanted to like the shoe as I love racing in the Adidas Rocket and Adios shoes and wanted a slightly more substantial shoe for long distance training.  While it is certainly more substantial than the Adios (i.e., longer life), it is just simply much too firm in the forefoot to be comfortable for me.  Found the Lunaracer to do the trick for a cushier ride on longer distance training runs.
