SCARPA Size Chart


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 the 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-moulded 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
