How to Measure for Trail Running Shoes
Foot Length: Measure your foot from the back of the heel to the tip of your longest toe.
Size Up: For trail running, consider going half a size larger than regular shoes to allow room for swelling and thicker socks.
Try Both Feet: Measure both feet and use the larger measurement for sizing.
