Available in either mesh or waterproof styles, the fourth iteration of the isoSeek provides a firm and stable ride that our test team recommended for those seeking cushioning, protection and motion control, especially for runners who have a heftier stride. The weather-resistant seamless upper had an enveloping fit with ample room in the toe box. The midsole and outsole combined for a rigid ride that testers appreciated on rocky trails, but they found the firm dual-density EVA midsole had limited flex on more moderate terrain.

Tester’s Take: “I enjoyed the rock protection of the stiffer sole, the meticulous design of the soft upper that felt like my foot was wrapped in a Lay-Z-Boy, and the eye-grabbing aesthetics made the IsoSeek the life of the party!”
