The first thing to be aware of when selecting shoes is the shape and fit. Before your foot can receive any benefits from the shoe, it must be the proper size for your foot. Furthermore, the numeral sizing system that our society has established is only a prediction of how a shoe will fit. Shoes labeled "size 9" can vary greatly in actual size depending on the brand.
The LAST is the shape or mold around which the shoe was formed during production. The last dictates a shoe’s width, length, depth, shape, and many other details that greatly impact the fit. Unlike many shoes available today, OOFOS are built on an accommodating last with more-than-average room for your toes to spread out naturally as they should. From the last, the rest of the shoe can be created and assembled.
