If a snowboard boot is packed out and too big or the support is too soft, riders can try to compensate by clamping down the closure system and binding. As a result, the pressure applied to the top of the foot can cut off circulation and lead to numbness.
On the other hand, riders who size down for a better heel hold can face the same issue, especially if the boot is stiffer and doesn’t pack out as much as they anticipated. Furthermore, some stiff designs and particular shapes are not ideal for certain foot shapes and can decrease blood flow.
Make sure you properly measure the length and width of your foot and try on various boot sizes at a retail store. Adding a new insole, J-bars (also known as l-pads), C-pads, ankle wrap pads, a foam narrowing pad, or boot-fitting foam can help snug up the boots in the right spots without downsizing.
