How do I make sure I purchase the Correct SIZE?

HOW DO I MAKE SURE I PURCHASE THE CORRECT SIZE?  DO NOT rely on your Shoe Size!  There is too much variation between Shoe Brands these days! To ensure your purchase the correct Size - Please stand on a Ruler and measure your foot. We have listed Sizes in CENTIMETRES and MILLIMETRES. Please compare the length of your foot against our Crazy SIZE CONVERSION GUIDE below. IMPORTANT: The Size listed in cm and mm below is the length of the Innersole inside the Skate - if your foot measures 25cm or 250mmDO NOT order a 25cm Size - this will  be too small. Allow 5-7mm for a good fit - If you want to allow for growth room - we suggest a maximum of 20-25mm.
