Men's Footwear Size Guide

Measuring tips

Take your actual body measurements as they are more accurate than measuring over your clothes or shoes.

Feet: Use a ruler or tape measure to measure your foot (from the heel to the tip of your longest toe) Be sure to measure both feet. Many people have feet of different sizes. Fit to the larger of the two.

Remember, feet can expand over a quarter size during a full day's walk so ensure you get the right fit.

Brilliant boots. They give great confidence climbing and descending on uneven and loose surfaces. Only took about 5km before they felt broken in but they were comfortable up to that point. Perfect for a day in the Cairngorms.
