What are the pro's and con's of these soles? For a long time I've been familiar with Vibram soles. Learning about high end English shoes, I see names like Dainite and Vendtschoen. Has Vibram surpassed these in terms of durability and comfort? Why are the good British shoemakers still using them, however? Do they have advantages? Also, how to you get repairs on Dainite and Vendshoen in the US? Lots of US shoemakers will replace Vibram with the same brand, but I doubt they've heard about the others.
