Hi. If this has already come up, sorry, and please feel free to move me. I got a couple of pairs of 40s sandals recently both of which have a split on the inner side of the sole of one shoe, just about where your foot bends to go towards the heel. That's not the paper insole, the actual shoe. The split doesn't show on the outside yet, and I'm wondering if anybody has found a way to brace damage like this? The sandals are otherwise fantastic, and I'm sure they would hold out for a few more light wearings, but I'd be a whole lot happier if I could fix it. I've taken one pair into a local cobbler who says he can't think of a way round it, but he's definitely not a vintage shoe expert. He has come up with putting superglue or similar along the crack as a kind of weld, but really thinks the shoes have had it. And has anybody found anything other than castor oil to rehydrate vintage leather - it's great I find, but wonder if there's something even better?
