I have been wearing Teva Omnium's now for about three Summers. It all began when I began volunteering at a camp and you had to wear "closed-toed" shoes....that is, no flip flops.  These fit the bill perfect. Closed toe as requested, with a rubber inner foot sole and outer tread much like an athletic shoe, they also are MEANT to get wet....go tread out in the river, and within the hour they damp but not wet,and about 4 hours later they are totally dry.  They also include,as part of the rubber, a zinc compound to fight odor and bacteria build up.

There are multiple hook-and loop straps for you to make adjustments so the fit is perfect.  I wear these now as my primary shoe in Spring Summer and Fall. If they start to smell a bit and get a little dirty, just bring them with you in the shower and scrub them down good with soap or body wash.

A great product  You will not be dissapointed.
