Wow these come with everything but a rocket booster. I'm not up to date on wheels but I know in my day I would have given you my best friends lunch for them. Seriously, a red wing shoe as well.
These could last another 50 plus years. I see only slight signs of wear. One eyelet at very end needs popped back in. Could polish them just a little for a new skate look or keep this gently broken in look.
As for size I can't find a printed size so check photos for some measurements and condition.
