i bought the keen H2 sandal so i will have a water sandal for the summer. also it is nice to have a closed toe sandal when gardening or doing work around my house.  i have not had a chance to wear this sandal in the water yet.  the keen H2 sandal is very comfortable, with lots of room for my toes, which i like.  i had the brown/turquois sandal and returned it for the grey.  i think the grey looks better with more of the clothes that i wear.
