All SCARPA non-plastic footwear and our 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.
SCARPA ski boots use Mondo sizing.
SCARPA ski boots break on the half size, this means that a half size shares the same shell length as the whole size above it but the liners are lasted for each 1/2 size. For example, a 25.5 and 26.0 are the same shell size but the respective liners come pre-molded to the half size.
Some skiers may want to downsize up to 1 full Mondo size, depending upon personal preference.
SCARPA plastic mountaineering boots are based on the UK sizing scale, which has equivalent increments to the US sizing scale.
1 UK whole size = 8.4 mm = 0.33 inches
1 US whole size = 8.4 mm = 0.33 inches
