Thank you for viewing. SCARPA Boostic (old model) Size: 38 1/2 I liked this model, so I bought a spare, but I'm selling it because I've stopped climbing. I've put my feet in them a few times to try them on, but otherwise, they are unused. Good for slab and overhanging walls, and I think they are especially good on granite. "I liked this color scheme." There must be people who feel that way... Thank you.
