361° SPIRE 2 - The update to the 361° Spire retains the strengths, with an eye to making improvements to all aspects of the shoe. The upper sticks with the quality stretch mesh, while upgrading the traditional overlays with well executed welded support. Internal structure now supports the midfoot while reducing a bit of weight, and a light, stitched counter replaces the thermoplastic heel support from round one. The very effective Qu!kFoam midsole with its firm but bouncy ride is unchanged, good news to fans of the original. The outersole continues with carbon rubber in the heel, a blown rubber perimeter through the forefoot, with the lateral side layered with Qu!kfoam for a softer feel. A thermoplastic shank provides torsional support. Round two adds polish to a shoe with a ride as its strong point, taking it up a few notches in quality and performance. Updates the Spire.

Testers: "I enjoyed the original but was more than a bit impressed by round 2. Cushy ride that is great to run in, and the fit and durability make it a great mileage shoe."
