How to Measure

Stand on a sheet of paper with your heel against a wall and mark the tip of your longest toe. The distance from the wall to the mark is your foot length. For a standard fit, Nitro recommends adding about 10 mm (men's) or 15 mm (women's) to your foot length and choosing the matching Mondopoint size. Boots will pack out a little over the first few days of riding.

Fit Tips

  • Snug fit: add 5 mm (men's) / 10 mm (women's) to your foot length. Best for narrow feet or minimising toe and heel drag.
  • Standard fit: add 10 mm (men's) / 15 mm (women's). Right for most riders and leaves room for heat moulding or aftermarket insoles.
  • Roomy fit: add 15 mm (men's) / 20 mm (women's). For sensitive feet, thick socks or cushioned custom insoles.
  • Unsure between sizes? Come in-store at 435A Bridge Rd, Richmond for a boot fit, or call us on 03 9421 2293.
