Whats the difference between SL-1 and SL-2 lasts?
A. The SL-1 last is made to accommodate a foot type that is typically long and narrow, with a smaller arch, and more shallow in depth. An SL-2 last, on the other hand, is made to accommodate a foot type that is typically shorter, wider in the toe area, thicker in depth and has a higher arch. More on Foot Types.
