Yes they are extremely good value - especially for a full custom boot maker! Plus their styles are really classy and the leathers and workmanship are first rate.
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...
Fernando Berlin makes all kinds of awesome boots in tall sizes too: www.fernandoberlinboots.com
Arollo has some of their boots available in big sizes: www.arolloboots.com
Nice italian heels are sold by Shoebidoo Shoes: www.shoebidooshoes.com
Be advised that Italian shoes and boots tend to run large. Typically you could fit one size smaller than your normal (non-italian) fit.
