These are Olson curling shoes. They're old, so there's some wear and tear, but they're still usable. The slider is the thinnest 1/16 inch, which is suitable for beginners. Curling shoes are expensive, and many people hesitate to buy expensive ones when they're just starting out, so how about these as a first pair for those who are thinking about trying curling? The anti-sliders are not original, but are the type that can be used on both feet for hard line. They're a bit tight, but I think they'll work fine for beginners. If you're concerned, I recommend buying a larger size at Ishida Sports, etc.
