Over the years Ive had quite a few requested to make an increase of the 5 inch boot I on the D'Etna boot I already make. The trouble for me was that I had to start the designing the shoe last from scratch again. You can see quite a different in the regular D'Etna boot and the pair shown here on the website. The new version has a double leather sole (8mm) plus a 5 mm rubber have sole) the Insert is made from both PU rubber and EVA Hardened Foam. I will wait for further inquires for the 5 1/2 - 6 inch. Im sure they will arrive soon.
