There are tons of closed toe flat espadrilles out there right now, and of course they are all on sale. I've tried a half -dozen different brands on, and every single one of them is way too loose in the heel. Walk right out of them. Toe box is fine , but all of this soft leather , canvas etc doesn't make for a great fitting flat. Has anyone found one that fits snugly and stays on? I have totally average feet - maybe a tad narrow but nothing dramatic. I don't see an insole helping , but maybe I'm wrong .
