I agree! I have 3 pairs of boots made by Jean Gaborit. None of those have high heels, but the quality is very good. I bought a pair of JG thighboots 21 years ago and they are still in great condition.
Also, they appeared to be only company willing to make me a pair of kneehigh boots suitable for wearing in public and for a price that didn't require a second mortgage on our house...
