Based on customer feedback we can say these shoes run LARGER than you might be used to. Generally, we recommend you order the next available size down to what you typically wear. For example, if you wear a size 10 or 10.5, order a 9.5 since thats the next available smaller size.
Use a ruler to measure from the back of your heel to the tip of your longest toe, measure barefoot.
TIP: Place a flat ruler on the floor and against a wall, next, place the back of your foot against that same wall and stand on top of the ruler. Look down to read the distance to the tip of your longest toe.
