The insoles of these shoes are flat. I used to be able to wear those flat shoes when I was young but now, (maybe from wearing shoes without arch support,) I can't unless I want to make an expensive visit to the podiatrist. My gripe is, why can't the manufacturer just say in the description, no arch support, or maybe, better yet, include an insole for people who need it. It's cheap when it's done at the factory but after market it can cost as much as $80 although one can find adequate insoles with arch support for as little as $20. I'm giving the manufacturer and Online Shoes a zero for not putting this info in the description.
