Low Volume Hardboot?

Hey Folks,

I have been wearing the Atomic Backland Pros for this season and unfortunately I just can’t get the fit right. I find the shell to be too high volume for my feet. When I add the volume shim, I start to get blisters on my heels. What other boots would y’all suggest I try? I run pretty warm so I am hesitant to get a thicker, warmer liner. Thoughts?
