I ordered these to help alleviate plantar faciitis. I found that they didn't offer any more support than a regular pair of crocs and were too loose fitting to provide proper support. I returned these and bought a pair of sandals from the Walking Company (Abeo), plus a Mueller arch support for other shoes. Combined they solved my problem. The key with PF is to never, ever go barefoot and make sure you have good arch support until fully healed.
