These rare beauties are in amazing condition. These are mid to late 60's from Europe and fully crocodile embossed leather is in excellent vintage condition. As seen in photos the wear is so minimal even on the soles.
They are an EU 38 or should be a US 7.5 but had my daughter try on with socks and tights her true 7.5 was tight so I would estimate that they would fit better at a 7 or even 6.5 with heavy socks.

60's European Go Go Boots's women’s brown, leather knee high.

Very Good condition, size 6.5 and 7.

Detailed measurements:

Length Of Sole - 9.66 inches
Heel Height - 3 inches
Boot Height - 16.5 inches
