Adizero Boston 13 vs Adizero EVO SL 1

The Adizero Boston 13 is adidas at its most versatile: a firm, fast daily training shoe built to handle tempo work, threshold sessions and steady miles in one pair. It is not a race shoe and it is not a soft cruiser. It sits in the middle, the workhorse you reach for when the session asks for pace but you still want a shoe that lasts. At 254g it is on the heavier side for a tempo running shoe, and you feel that weight on truly easy days, but the trade is a platform with real durability and a planted, controlled ride. The internal rod system keeps the forefoot snappy and stiff, so when you push the pace the shoe pushes back. Compared with the lighter, livelier Adizero EVO SL, the Boston is the more rugged, do-everything option. If you want one shoe to carry your whole week, this is a strong pick.

The Adizero EVO SL is adidas taking its marathon race foam, stripping out the plate, and giving you a lightweight speed trainer you can actually run every day. At 224g it feels closer to a racer than a daily shoe, and that is the whole point. This is a running shoe for the runner who wants one pair for tempo sessions, strides, parkrun and the odd long run, without the rigid, all-or-nothing feel of a carbon racing shoe. You get lively, propulsive cushioning and a low 6mm drop that keeps you up on your forefoot. At an RRP of £150 it undercuts most super-trainers and plated tempo shoes, which is a big part of why it has been so popular. In our view it is one of the most versatile shoes adidas has made in years. If you want the plated race-day version, the Adizero Adios Pro 4 is the sibling to look at.
