The adidas Solarboost is immediately comfortable. We mean seriously comfortable. While the Energy Boost felt good, it was missing a bit of the step-in, hold-onto-your-foot fit that this version has. On the Solarboost, the Boost foam underneath makes the shoe feel like a therapeutic foam mattress for you feet.
Adidas kept the lacing classic and straightforward, though one tester used the marathon loop lacing technique to lock in her heel. Cinched down, testers didn't experience any heel slippage.
The shoe is also roomier in the forefoot than the outgoing model. Designers added volume to the toe box, which is noticeable right away. The shoe gives your feet enough room to splay without feeling sloshy inside.
One tester who put more than 100 miles on the shoe said, "All around, it's a perfect fit."
The Techfit upper is soft and snug for a sock-like feeling, and the stretchy mesh forefoot and cushioned tongue offer a precise fit that's as comfortable on short days as it is on long hauls.Shop Women's adidas SolarBoost
