I have a pair of water shoes that came from a box store to walk along the shoreline in, and they work out well for foot protection. Not real chunky or clunky, decent grip if stepping on something slimey as you might find at a boat launch. However, I don’t like wearing shoes as I like to flex my tootsies and this includes while paddling.
I would always by my dress shoes an the next width and actually pretty much all shoes that way. If I cant get a double or triple wide, I go up a 1/2 size.(old shoe-dog trick). Sandals can be a difficult fit as the little guy tends to flop out, depending on the straping. Even sandals though, do not allow for the flexing I like. I have also discovered that putting the water shoes back on and snugging to fit can be a bit ackward while still in the boat.
The 3T items look interesting. Have been reading the threads I can find. Of course being up here in the retail wasteland, not many places to shop, so not many chances to gauge fit.
Any preferences, thoughts etc? Does your preference run short, narrow etc? Do you size up to the next full size etc?
Once again I shall be in your debt.
