Basically, the Splay Whiteout is a well-engineered, zero-drop, natural foot-shaped, quite wide-toe-boxed, and highly flexible shoe. Splay improved on their original "white-canvas-looking" prototype by making the bottom out-soles of Whiteout totally flat, and most critically: flat right to the outer edge, creating a far more stable out-sole foundation (this is in sharp contrast to the original model that was rounded toward the out-sole edge, and made that earlier model less stable when turning and/or changing direction). The "roof" of the toe-box is higher than the original -- which is an improvement, but could still be raised a bit further to accommodate more (buyer supplied) insole options. And, of course, Splay needs to adopt "half-size" options, as many people (like myself) require a half-size (for me, a 12.5) for a proper fit instead of "the next size up" (for me, a 13), which can cause slipping while walking. Otherwise, it is a very good health-focused "barefoot" shoe that comfortably accommodates Dr. Ray McClanahan's "Correct Toes", which I always wear with any pair of shoes.
