I can recommend them very strongly indeed.
they do vary from almost literally barefoot where each toe has a slot, as it were
to ones with a reasonable amount of padding underfoot and very widespread in the toe area. Just have a look by entering "toe shoes" in Amazon, to browse.
I recommend the latter strongly for most of us seniors, unless your feet are in very poor condition, take advice
(I wear them at the gym, and at home, where of course it's not just indoors but the floors are flat), wear indoors initially.
They really do help with giving you toe spread out. I got mine on Amazon and yes often buy 2 pairs different sizes and send one back. Advice is to avoid sellers that don't send you the shoes for a couple of weeks or longer difficult to return!!! - choose a firm that has a UK distributer.
If you buy a bit of a size up you can of course add a nice or a medical padded insert, as well.
