GLC, good luck with the surgery and the last phase of recovery!

I have a pair of men's wide NB Minimus cross-trainers, so I don't know if they're on the same last as the trail or road shoes? Anyway they are wide enough in men's wide, but the toe boxes are pretty pointy. Lemings are actually shaped like feet!

I've seen CorrecToes in a lot of drugstores with the foot care stuff, you might check. But, IMO it all comes down to shoes that fit. If your shoes are forcing your toes together, then it seems to me that trying to force them apart from the inside is just going to aggravate any trouble you have with ingrown toenails, bunions and bunionettes. Once I finally found shoes that fit (plus started work on foot strength, mobilization and flexibility), my toes have reshaped themselves quite a bit all by themselves, even after 50 years of wearing shoes that were too small.
