DAoust 501's!! I had those too! They were with goldish blades...Titanium coated...they too were supposed to hold an edge better. I loved them, however I remember the day I out grew them, they hurt like hell. There was no inbetween with them as I recall. Great skate though..I'd love to get my hands on a pair of the old Daoust skates I had back in the 80s when I was growing up. They were so comfortable and I remember being so proud of them. Forget newer and lighter! Go retro!
