“Depending on sneaker, I usually wear a men's 11 or 11.5. My regular dress shoe is an 11. I bought size 11 of the mesh slip on water shoes and they fit perfectly, not tight at all. I went on a cruise and wore these on ship, in town, and on beach with sand and some rock. I found these shoes remarkably comfortable. With only 2 weeks of wear, I cannot comment on durability but they still look brand new. When wet, they dried quickly. As a snorkeler, I bought them specifically for getting into/out of water. Did not use them in any heavy rock areas for entry into water, but the hardened yet pliable sole on these shoes tells me they will work fine. The comfortable soft uppers with harder sole made them especially and surprisingly great for walking in and about towns in the ports of call on concrete, sand, ATVs..etc. I would definitely buy again.”
“Wore these everywhere - mud hikes, a short lava hike, beach, hotel, restaurants, etc. Took the soles out when I didn't want to have to wait for them to dry. For the money, best shoes I've ever bought. I never had a problem with junk getting into the shoes. However, you will need to stop and pick rocks out of the soles a couple times a day.”
