British Walkers? They made this model with some pairs having actual horned back lizard skin and others with faux. I believe these to be faux... but a very cool design nonetheless. The stamping is very well done.
Enzo is heavily influenced by US vintage shoe styles. This exact model of longwing was quite popular with both the canvas & a mesh for spring/summer wear in the 40's & 50's. I have a pair by Florsheim circa 1951.
