Dynafit AT tech fitting compatible 4 buckle boots, very good condition, $300 +shipping
Boots have Gfit heat moldable liners in them, have the Dfit heat moldable liners as well, you choose one or the other.
These are one of the lightest 4 buckle boots on the market, they are great boots but are tight on my feet. No shell mods have been done. Liners each have been molded once, they can be reheated several more times.
