I wore out two pairs in the 1970s. When they became unavailable, I found some Sidi shoes which I wore through the early and mid 1980s - they were made of chain-woven red nylon thread, they were very breathable, and black smooth-leather patches over the toes, outer metatarsal region, and heel. Negative heels, like the BB. They had a very stiff hard black rubber/plastic sole, and I wore them daily for maybe six years - commuted and toured in 'em. Great with toe clips. No provision for SPD cleats. I still have 'em, but the BBs are long gone. I picked up a pair of Shimano shoes which worked OK with toe clips more recently (meaning 10 years ago!). If BBs were still around, yeah, I'd have a pair.
I'd need a time warp though!
