Find a Shoe Shaped for Your Foot

Running shoes are built on a “last,” which determines the shape of the sole. There are basically three shapes of last: straight, semi-curved and curved.

The greater the curve of the last, the more flexible the shoe is likely to be. Conversely, straight-lasted shoes tend to be less flexible. So, a runner who needs motion control in his shoe usually does better with one built on a straight last.
