For length measurement – Place your heel flat against a wall.
Pro Tip : A picture is worth a thousand words. Along with your measurements – snap some pictures of the measurement process and send them our way SkatersEdgeShop@telus.net (please include First & Last Name as is on form so we can cross reference). This allows us to get a visual idea of how and where the foot carries the width and where you may experience pressure points.
If possible taking a picture of the skater on their current insoles can also be very helpful!
