I am very pleased w/ my Speedo zipwalkers b/c I do water walking in the pool at the gym nearly everyday, and these are perfect for that, both lightweight and sturdy.  My only grumble would be that it took a verrrrrry long time to arrive at my house, they went from Kentucky, to Sacramento, to Atlanta, to Charlotte, to Greensboro, to Raleigh, and all this travel time took a long time. I am baffled b/c to ship straight from Kentucky to my home would've taken 3 days---tops.
Other than that----they are a GOOD product, perfect for what they are designed for.
