Hello Equestrian leather workers. I have a client who wants a pair of custom leather bell boots made.  My question is what would be a good choice of leather type for this application?  Chrome Tanned. Bison. Buffalo. Heavily oiled Veg Tanned?   These are the Veg Tan prototypes I made to check the fit and to workout the proprietary no turn knob feature.  My concern is wet conditions. Any and all suggestions are appreciated. Thank you! Silverd
