Scarpa Shoe Size Guide

All SCARPA non-plastic footwear and the Alien 3.0 uses European sizing.

1 Euro whole size = 6.6 mm = 0.26 inches
1 US whole size = 8.4 mm = 0.33 inches
The 30 Euro sizes below cover the same size range as 24 US sizes
Euro sizes provide a better, more precise fit for your intended use
For mountaineering boots, upsize (1/2+ sizes) depending on desired fit.
