The latest version of the Boston running shoes is balanced and improved. While the upper is not the best from Adidas, it does its job well with breathability in the toe box and on the sides of the shoe. But the upper is stretchy which feel great when running. But even with a stretchy upper, it is highly recommended to go half a size up to avoid a shallow fit. The feel of the midsole is similar to the previous version. It is great for running on all surfaces. Depending on the distance, the midsole is right for race day as well. With a solid ride which is not too soft, the shoes feel great even at a higher pace.
