These are Alpinestars riding boots, size 3.   Missing one of the top straps (see photo 1 - right boot in photo) that secures the top of the boot and I don't know if that can be replaced or not but it is gone. Velcro does secure the top of the boot at the same place where the missing strap is so boot isn't going to fall off or be loose.  Boots are in good shape but were worn quite a bit by rider 7, 8 and 9 years old and then he outgrew them.   I know that my kid loved them and he loved to wear them so I felt good about that as they are good for his foot and lower leg safety rather than not wearing them because they didn't feel good.   No problems shifting gears with these either.

No torn leather, no holes, Velcro works fine.    I'm not an expert but I'd say that bottom rubber of boot appears to be about 20 - 30% worn down, perhaps less as this rubber is very hard.   Boots were used in dirt and sand and not on pavement.   thanks.
