The soles I linked attach with shoe glue & stitches.
I was going to use Shoe-Goo along with stitching.
I did find a seller on etsy who makes her clogs with cork soles
But I was looking for a different sole.
In my knitting class, I met a mom whose husband has made their own shoes and we got to talking about soles. I may ask for her advise.
I may end up making my own sole out of a combination of cork and rubber the way the Stegmann and Haflinger wool clogs are.
I need to get the clogs made first.
Having difficulty reading the pattern.
