Bontrager Shoe Sizing
The Bike Shoe Size Conversion Chart below shows how Bontrager's sizing compares to US Men's and Women's shoe sizes. However, because the fit of Bontrager cycling shoes is optimized for on-bike comfort and performance, your Bontrager shoe size may be different than that of your street shoe or athletic shoe sizing. For best results, visit your local SCHEELS store.
Determining Your Bontrager Shoe Size
To be most accurate, use a Brannock device to measure if you have one. If you don't, follow the instructions below for at-home sizing or stop by your local Trek retailer or SCHEELS to be properly measured.
Step 1
To measure your feet, start by wearing socks you typically ride in and lay a blank piece of paper on a hard, smooth surface.
Step 2
While standing, distribute weight evenly and have someone trace each foot with a pencil taking extra care around the toes and heal areas.
Step 3
If you are working alone, sit down on a chair and lean forward to shift more weight onto the foot you are going to trace.
Step 4
On your outline, measure the distance from the heel line to your longest toe line and cross-reference with our sizing chart above. If your feet are different lengths, use the longer of the two measurements.
