Within 5 minutes of being in the water the glue disolved that held in the inserts and they begun to crumple up under my foot making them extremely uncomfortable. I removed the inserts think that would help however that just made it worse. I continued to wear them for roughly an hour when the stitching that held the sole to the fabric begun to come out at this point I got frustrated with wasting my money on a pourly made product and threw them away.
