|PRO||Heat-mold these low-volume insoles in the store for a custom fit; EVA pads support the heel and ball of foot while a flexible arch allows mid-foot articulation for a natural stride.||These soft, squishy microfiber shoes are ideal for camp or travel; they pack flat (less than 2 inches thick) for easy stowing; 3-mm-thick EVA insoles provide comfort and cush.||Superfine, lightweight yarn yields more loops per inch, which provides excellent, long-lasting cushioning.|
|CON||Pricey; not sold online, like some DIY heat-moldable insoles||No midsole, so they lack support on hard surfaces or for long walks.||We wished for more padding around the anklebones.|
Midsoles—which layer various combinations of materials that are glued, injected, or heat-bonded between the sole and upper—are the heart of any boot. Foam-like EVA (ethylene vinyl acetate) is springy for supreme cushion. PU (polyurethane) is a denser, more durable, and more supportive foam. TPU (thermoplastic urethane) adds even more stiffness and structure.
