HOW TO USE THE FOOTWEAR TABLE
The key measurement used to arrive at the correct footwear size is the one between the heel and tip of the big toe. Choose the size for the measurement immediately above in the table. Shoe covers and socks have been designed to be compatible with Spiuk footwear. Therefore, in principle we recommend you use the same size shoe cover as you would for footwear. The given size in mms would correspond to that of the inner sole as it is understood to be the best way of verification
