Ecco departs from its earlier running shoes to take advantage of its manufacturing strengths. The BIOM A uses a direct-inject polyurethane midsole that adheres to the upper while still wet, a technique that isn’t possible with EVA. The upper is available in either a synthetic textile or the more intriguing yak leather (shown). The flexibility and fit of the leather upper is surprising: it breathes to keep the foot comfortable and even sheds water effectively. The shoe’s low profile requires a little physical adjustment, as does the level of cushioning. The shoe comes with 2 insoles (PU and EVA with PU inserts), but it’s designed to transfer much of the cushioning action to the muscles and connective tissue of the runner’s legs and feet. The flexible TPU outersole adds to the durability, and encourages the natural motion the shoe is designed for.
Testers: “Felt very snug, almost felt like a racing flat or a road race shoe. The first time I wore them, I absolutely hated them; however, after several runs I’ve grown to like them and the fit and feel a bit more. The shoe has very minimal cushion and support and takes a while to get used to. So far, they’ve held up fairly well and haven’t had any problems with the durability.”
