Very comfortable! I have bone spurs in both heals. Doctor suggested Crocs no other name brand shoe was suggested. This is replacing the first pair that I've worn out that was made in China. This new pair is made in Mexico and has a much better traction/grip on the sole. After the first week I notice the stitching on the leather beginning to unravel. Instead of returning them, I purchase some stop fraying. It now looks like there's wet spots on the shoe. Store needs to contact manufacturer about stitching issues. I've read another person having the same problem. In addition the arch on top of shoe is so high that the strap no longer folds up and lays on top of the shoe, like the old pair did.
