Alt tag: Drestiny's step-by-step guide on how to measure your foot for the best fit. The guide includes five steps: 1) Place a sheet of paper against a wall with your heel at the edge. 2) Mark your longest toe and measure from the wall to the mark. 3) Repeat on both feet and use the larger measurement. 4) Match your measurement to the size chart. 5) Tip: If you are between sizes or have wide/thick feet, choose the next size up.
