Click on the "L", etc. on the STP description & it will show the size for men's and women's shoes. These sizes are pretty accurate. Every pair comes with two silver and two black TABs for you to use for additional customization. However, there are no instructions for how to do it. When I contacted the manufacturer, they said that customization needs to be done by a trained professional...which makes buying them online problematic.

If you hover your mouse over or click on the sizes the corresponding numeric size will be displayed.
