I wear an afo by Otto Bock called “WalkOn.” I wear them in the water all the time, with some canvas tennis shoes or some wet suit booties. The booties didn’t work to well when I put the afos in the booty and just stepped in on top of the afo. Then I tried putting the afo in the booty and put an insole from my tennis shoe on top of the afo; that workeked just fine. The afo is carbon fiber so it’s light, cool, and comfortable. The top velcro part dries quickly but I do have a couple sets so I can change them out if I need to.
