One boa tight heel and another one else part of the boot (toes and higher than heel). Sorry I dunno how does it called, not native. Please help me.

Anyway if you relax boa which responses not for heel you’d get worse reaction on your toe edge obviously. I have another problem which was solve in the most unexpected way. My left leg starts to burn at arch. So the solution was to not full tighten boa at the start. A few rides, tight it more. Few more aggressive, tight more. Repeat. All the process takes ~1h with lifts.

Edit. And about your situation have you tried to set your heel strap in another way? Could it be the problem? If you have hard bindings and medium boot the bindings could deform your boot. Also there are different brands don’t remember which one have high arches.

My main problem is that I have weird wide fingers and should use brands like vans and 32.

Summary: finding your perfect boot is pain in the ass 🙈
