Buffalos sure are tough things. Seems they are no longer made. Those deep grooves in the sole would make for an interesting experience. Would love to feel my hard tip having a ride along the long groove with the edges of the side grooves pulling and tugging at it.
I like the yellow flowery clogs with deeply treaded soles. I'm looking for a pair of slippers or clogs with heavily cleated soles that my wife can use to "massage" me. It believe it would cure my lower back problems in addition to providing sexual stimulation.
