One of SuperFeet's most popular inserts year after year, BLUE packs exceptional support into a thinner design to improve the overall fit and comfort of a wide range of footwear. Responsive closed-cell foam provides a firm foundation of support for lasting comfort, and the medium-profile shape puts support right where you need it while taking up less space in shoes. The structured heel cup positions your heel to naturally absorb impact, while the medium arch support provides stabilization to reduce stress on your feet, ankles, knees and back. Engineered to keep their shape, BLUE insoles deliver reliable performance for up to 12 months or 500 miles, whichever comes first.
