To find the right shoe size for you, all you need is a blank sheet of paper and a pen. Follow these steps:




Insoles come in various shapes based on brand and the shoe’s purpose, affecting width, depth, height, and overall fit. Trek and Bontrager offer shoes designed around several different insoles to meet all riding goals for maximum performance. The types includes:
This last features a snug, high-performance fit optimized for the rider’s movements. It replaces the Bontrager inForm Pro insole but is slightly wider at the ball of the feet, providing a better fit for more riders.
The Trek Comp last offers a performance fit with a bit more room. It replaces the Bontrager inForm Race last and has been updated to better fit riders’ feet by widening the ball of the foot.
This is a performance-fit last with a slightly roomier fit from the ball through the mid-foot.
A comfortable last with a flatter foot position, providing more versatility and utility.
A relaxed, roomier fit similar to a cross-trainer, combining comfort for both on-bike and off-bike use.

Place your bare foot in a small amount of water, ensuring that the entire bottom of your foot is submerged in the water.

Gently place your wet foot on a dark piece of paper so that it leaves a visible impression of your foot arch.

Dry your foot, then compare the impression with the Trek Arch Index below to determine which of the three insole heights best fits your arch shape. Repeat these steps with your other foot.
