Updated: I have two shoes that I alternate wearing to water aerobics 3x per week. I wash them in a washer and air dry. I also have cruised with them, wearing at the pool and in beaches. Even with all the chlorine and washing exposure, they are holding up perfectly.One has developed a 1/4" separtion near the toes but I consider that just age and normal wear. Just bought a third pair to cycle into the rotation.Also I have a condition that reduces feeling in my feet. With bare feet I am very unsteady. These shoes help me be safer on wet pool decks.Original: Purchased for water aerobics so I wanted a snug fitting shoe. I wear a 9 1/2 so bought a 9 first but too large. Returned for an 8 and was a little long, but seemed OK after wearing a few times realized I would trip on the toe while walking so bought a 7. It was perfect. I like the lacing to adjust the fit.
