On this page you will find the Flex Boot size chart.
Flex Boot Standard Fit
Flex Boot Wide Fit
Please note: with the new WIDE sizes, we consider them to be more accurately described as SHORT. For example, the 110 WIDE actually has the same width measurement as a 110 STANDARD fit boot, but the length is shorter. This gives the 110 WIDE a more rounded shape.
