Back in the early 1970's I had a pair of ankle high, lace up mocs made by Walter Dyer. I wore either them or the sandles I made all the time. I don't know where they went though. Yours look quite comfortable.
The guy I learned leather work from in Savannah learned from Walter Dyer and DD Holiday from Jacksonville, Fla. Together these two guys used to make dance shows for Isadora Duncan back in the 1920's and 30's. The sandles we made back then came out of the Bohemian era by these two guys.
