A versatile daily trainer with a firmer, stable platform that handles easy runs through tempo work and long runs, though some testers find it less exciting than Adidas's own Evo SL. Fit improves over the Boston 12, with a wider forefoot, but the midfoot runs snug and sizing up half a size is often needed.
A jack-of-all-trades super trainer that does everything well without excelling at any one thing; the perfect update for fans of the Boston 12, though the Adidas Evo SL makes it hard to get excited about.
Best for: Runners who want one shoe that can handle daily training, long runs, tempo, and even race day reasonably well — especially travel or one-shoe runners, and bigger/heavier runners who will load the rods more.
Best for: Longer-range training or daily driving, especially autumn/winter when lighter Adizero uppers aren't enough
Outstanding value at GBP 140 with excellent fit, grip, and durability — the desert-island pick over the Speed 5 for the reviewer.
Best for: Value-minded daily training and tempo work for runners who want a cruise-y, durable ride.
A well-rounded, versatile daily trainer that EDDBUD sees as a sound and consistent performer with a wider forefoot and refined upper, making it suitable for a broader range of runners than the shoes it's compared against.
Best for: Versatile daily training for runners who want a wider forefoot and a consistent performer
A big but subtle update that makes an already great shoe even better; superb value and one of the best shoes EDDBUD has tested in 2025, covering many use cases from easy runs to marathon pace.
Best for: Versatile daily trainer for easy paces through marathon pace, including long runs with faster intervals.
A genuine improvement over the Boston 12 with a softer ride, better upper and tongue, and good value at £140, but it's a hard sell against Adidas's own Evo SL.
Best for: Everyday runners wanting a super trainer that can handle daily miles, tempo work, and race day.
#5 long-run shoe. Hard to categorize — Kofuzi puts it here for long runs with some pace.
A solid, good-value super trainer with a firmer, denser ride; works well for faster efforts but feels less natural and versatile than the Speed 5.
Best for: Value-focused runners looking for a firm, snappy fast training shoe that also serves as a companion to the Adios Pro 4 for racing
Tommy sees the Boston 13 as a very good, stable and durable faster-training shoe that suits runners who prefer firm responsiveness over soft bounce, but he finds it less enjoyable and versatile than the Evo SL.
Best for: Runners who prefer a firmer, more responsive and stable shoe for faster daily sessions, intervals and tempo runs up to around 10-15K.
Compared to other road speed training in the same lane.
