Should last longer than two months. I figured the chain would weight down the pods causing my pods to fall out of my ears but I had none of that. The sizing said the small was equivalent to size 7 - 8. Then I did the personalized EQ via the Soundcore app. But these shoes are still pretty darn beautiful. 2 at the stem, leaving only a small 26. I’m a pretty solid girl and my natural waist measurements is 44. I do not know about arch support they are fairly flat inside, but my feel are more on the flat side so they work for me. I highly recommend these, theyre just as advertised. DO NOT BUY THESE!
