No, shell was made for blade sharpening strops. If you're used to Alden shell they put this shellack over it, which makes it more water resistant. Also, AE puts some weird finish on theirs with this spray gun, which even on their calf makes for a weird finish that is more difficult to get a good shine on. Shell on any other brand of shoes is mostly naked and has issues. Is it durable? Yes, but durability and aesthetics are not the same thing.
Pat, I don't wear Alden shells. As for AE shells, I had to use a sponge, a dauber brush, and water to clean the finish off. I had my Hanover recrafted by AE and when the shoes came back it was horrible.
Some crazy folks here on the forum had started to use Renomat to strip Alden shells down. Craziest thing I've ever seen.
As of naked shells, wasn't it obvious that shell loves wax? I wonder why would one wear shell outside without at least a light cover of paste wax.
