adidas Adizero Evo SL vs Adizero Boston 13

The adidas Adizero Boston 13 and adidas Adizero Evo SL may sit side by side in the Adizero lineup, but they occupy very different spaces. The Evo SL is an uptempo trainer that's unplated (apart from a partial plastic shank), making it a playful option for steady miles. Its midsole is full Lightstrike Pro, giving it a soft, cushioned, and energetic feel underfoot—perfect for runners who want a forgiving, bouncy ride that's smooth and fun. In contrast, the Boston 13 is a super trainer that brings a firmer, more controlled experience to the table. Its dual-density midsole combines Lightstrike Pro with a stabilizing Lightstrike carrier foam. The full-length ENERGYRODS on the Boston add noticeable stiffness and snap, giving it the kind of firm, quick turnover that suits structured speed sessions or marathon-pace efforts for runners who like a classic responsive feel that's also very stable.
