The secret lies in a material that Keen calls ergomorphic foam — an off-the-shelf polyethylene that is blasted with nitrogen. For years, medical-supply firms have used this material in shoes intended for diabetics, who must avoid developing blisters on their feet that could, if neglected, turn gangrenous. But Keen, a competitive sailor based in Rhode Island and a co-founder of Keen Footwear, realized that the material might also appeal to kayakers, yachtsmen and other so-called amphibious athletes, by more snugly locking them into their shoes.

The ultimate in ergonomic writing. Precision adjustment dial allows you to set the shape of the grip from circular to an ergomorphic triangular shape, or any shape in between!

Mion also features a trademarked ergomorphic foam footbed Keen developed from a material previously used only in the medical field. "The foam will take the impression of your foot over a period of 12 hours of use, and then it stays that way," he said. "Thus, the name Mion; the product becomes yours."
