I'm selling these because my child has outgrown them. The bindings can be adjusted without tools (229mm - 336mm). The release value is 0.5 - 4.5, and it seems to be originally designed for junior standards. However, I used adult-sized boots with them. It's possible they are compatible with both, but I haven't tested them with junior boots, so I'm not sure. There are some fairly deep scratches on the sliding surface. The surface has a textured design, which seems to make the scratches less noticeable. Type: Skis Features: Rocker Size: Junior Ski Length: 140cm
