adidas adizero Boston 4 Product Review

Short Take

A light and nimble option for training or racing, the adidas adizero Boston 4 offers everything you want and nothing you don’t in a performance shoe.

Big Updates

  • Lightweight Upper: A new thin, open mesh increases flexibility and airflow around the foot while keeping weight down.
  • New Fit: Increased volume in the toebox makes the fit accessible to a greater range of runners without sacrificing a secure lockdown.
  • Carryover Ride: Despite slight tweaks to the tooling, the Boston 4 offers a responsive ride largely unchanged from its predecessor.

Road Test

While adidas may have your attention on one of their multiple large-scale product launches this year, they quietly slipped out the adizero Boston 4, the latest update to their neutral go-fast trainer. Though it may not be stacked with innovation, we think the Boston 4 is a solid performer worthy of its own hype.

The midsole offers a lightweight and responsive ride well suited for faster running, and though it sits on the firmer side, it offers a sense of protection ample for longer efforts as well. A decoupled heel unit helps soften the blow for those landing on their heel, though we found the Boston 4 to offer a great ride no matter your footstrike.

A notable change in this update is the tweaked fit - the forefoot and midfoot has been slightly opened to accomodate a broader range of feet, though the heel remains snug for performance and security. In addition, a thinner and more flexible mesh is used for a less constrictive feel.

Our testers loved the light-on-the-foot feel and the fast ride of this latest shoe from adidas. Whether serving as a lightweight trainer or long-distance racer, the adizero Boston 4 is a great shoe that will just make you want to pick up the pace.

Runners Say

Jonathan

“This shoe does everything a performance trainer should do. It provides adequate protection, is lightweight, and stays out of the way so you can focus on running fast.”

Joanna

“I’m a fan of the new mesh upper. It’s flexible, breathable, light, and holds the foot securely. What more can you ask for in a performance shoe?”

Taro

“As a runner with a slightly wider forefoot, the Boston 3 was a bit too snug for me. This update makes the shoe comfortable, without losing out on that performance oriented fit.”
