Fits true to size. Go to the nearest whole size if you take a half size.
In our size chart below we show the length and width of our removable inner soles. We strongly recommend you compare these to an innersole of a shoe you already own, by measuring it without pressing downwards.
Measure you feet by standing up straight on a hard surface with your heel against the wall. Put a piece of blank paper taped to the floor below your foot and have someone mark the longest part of your foot on the paper (or do it yourself if necessary). This is called ”heel-to-toe length”. Repeat with the other foot as left and right sizes might be different. Use a ruler to measure the heel-to-toe length you have marked on the paper.
