The inner boot's upper inside cuff & inside tongue are leather. The rest of the inside liner is a Gore-Tex fabric.
The welts (lip of boot) & sole are in very good condition.
The boot is stamped as a 9 1/2. Lowa website states they have "unisex sizing".
I think it is UK sizing, making these a US 10 1/2, because they are just a little snug on me, and my feet now measure US 11.

The Boots are crampon compatible, accepting step-in or strap bindings.
I have them with Silvretta ski mountaineering bindings.

Asking $75, plus $10 shipping. Thanks
