RealFoot Size Chart
Realfoot are a small business based in the Czech Republic who focus on the development and manufacture of barefoot shoes with a unique toe box that they claim offers the widest space for toes in the world!
They spent 3 years developing their sole unit which has a unique shape that is designed to give the foot space while holding it firmly in place. This means that the sole is slimmer through the heel & midfoot with a wide fan shape at the toes. There is a slight slope to it so very wide and square feet may need to take care with the sizing to ensure enough space for the little toe but there is so much width there we think it will fit the widest feet really well. They use the same sole unit for all of their shoes and boots which is 4mm thick and nice and flexible, a 1mm lug and a 4mm removable insoles gives an overall stack height of 9mm.
