The A$AP Rocky x PUMA Straycat runs a Vibram outsole that doesn't stop at the sidewall, climbing up onto the upper instead. The tread pattern comes off a tire, which tells you most of what the shoe is about before you get to the rest of it. Suede and ripstop build the upper with a chrome formstrip cutting the midfoot. Rocky worked it off a PUMA runner from the early 2000s.
