Never heard of a recovery sandal. I'll take a look but my knee jerk reaction would be that some company has devised a way to separate people from their money. Running is a very basic and natural activity that humans have done for as long as humans have existed. How long have these sandals existed?

I won a pair of recovery calf sleeves as a door prize during training for my first half. They were a big help after my first half, and totally unnecessary after my later halfs. I almost forgot about them after my first marathon, but they probably would have helped if I'd had them with me to put on after I showered.

I've never seen sandals specifically labeled "recovery." The local Fleet Feet sells Ooofos flip-flops that are reputed to be comfortable. As a male with large feet, I couldn't get them as flip-flops, but did buy a pair of Oofos clogs. They have good arch support, and they seem to have molded to my feet over time. They felt very, very good the day after I ran the Buffalo Marathon; but I don't think race recovery would be a sufficient reason to pay $40 or $45 for a pair of clogs. They do a good job of being comfy to wear around the house when my feet aren't up to handling being barefoot. But I think if I needed them regularly after running, I would be doing more than I should in training.

I'll tell you what.... I went to a marathon expo the day after I ran about 36 miles in the forest.

I tried out a bunch of different "recovery" sandals and they all felt sooooo goooood. The one I really wanted to buy they didn't have in my size.

I was driving home from a hundred miler (DNF at 75) and all I could think every time I got out of the car to pee is how much I wished I had those sandals.

I wanted a pair that looked like they were made out of a firm egg crate mattress.
