Tecnica Explosion EXP X AVS Ski Boots women's Size 7, mondo 26.0 in very good condition. We purchased these used and realized they were the wrong size. They appear to have straps connected to a heating system of some kind in the sole. We did not pull them out to inspect and have no way to test them. Bonus if you can figure it out! SPECIFICATIONS: Mondo Size: 26.0 Size*: 7 *- Mondo size is the actual size of the boot. The US size has been added for convenience purposes only. Please see size chart at the bottom of the listing. **Be sure to zoom-in on all photos and double check measurements prior to purchase** Smoke free, dog friendly home.
