I bought a pair of New Balance Men's SM720 Water Shoes, grey colored, 10 4E US just before embarking on a trip to Central America. I was looking for footwear that I would be able to go to the beach in and double as sandals while simultaneously providing me protection and support on a planned whitewater rafting trip. These shoes were the perfect fit and became my go-to shoes both during and since my vacation. They provide sufficient sole support but are otherwise extremely lightweight, open to airflow from almost all sides, but especially along the top of the shoe. Holes placed all along the bottom edge, near the sole, drain any water the enters the shoe and keeps your feet relatively dry, even while engaged in activities on or near water. The lacing system is extremely simple and easy to use, just requiring that you pull the laces tight and slide a plastic mechanism to the required length, locking them in place. The mechanism/excess lace is then conveniently tucked into a flap at the top of the shoe's tongue. I generally find myself slipping them on, pulling at the straps on the heel rather than engaging the mechanism at all. Altogether, I highly recommend them, as they were both quite useful and stylish. I even had one Latin American guy offer to trade me his similarly flashy (and probably significantly more expensive) pair of sneakers upon seeing my own. Note that I would recommend, as another reviewer did to me, that you purchase the shoes in a size wider than you may be used to. I purchased the 10 4E model for this reason, and though my feet are not especially wide, I feel like the regular size would have been a bit too narrow.
