Instinct lace. Size EU39 USM6H. I've worn them 2-3 times, but they're too tight, so I'm selling them. After purchase, I reinforced the area between the sole and the upper with Shoe Goo to prevent separation (it's not broken). Personally, I felt the sole was on the stiffer side. For reference, I wear La Sportiva Miura in EUR 38 or 38.5, and Scarpa in EUR 39.5. The soles are almost new, with sharp edges.
