I used to really love the Tide when it was Orthaheel but since it's Vionic Tide 11 unisex, they are very poor fitting and my feet just flop around. The straps are way, way too big. Width is good but footbed a bit short. I don't understand why they can't bring back the Tide and why they can't make a womens version that fits more to womens feet. This is the 3rd summer I've given them a try and the 3rd summer they're going back. Used to be a faithful Orthoheel Tide wearer but I think those days are over. Looking into Aetrex and some other brands now.
