For All Sizing Charts To order the right size  boot you first need to measure your foot. Remove your shoe. Either wear the sock you would skate in or no sock if you skate barefoot. Place a blank sheet of paper flush against the wall. Place your largest foot on the piece of paper with your heel touching the wall. Draw a line holding the pencil straight up and down at the end of your longest toe. Measure from edge of paper against the wall to the line marked.

Example: If your foot measured 10 1/4 inch or 260 millimeters you would order a size 8 or 41 boot. For all Powerslide Skate Models:
