This is my second pair of Teva Ominium sandals. I really loved the first pair. I wore them on a 6 week trip in Central America. I am a backpacker and enjoy hiking and walking. I put a lot of miles on these sandals in the rainy season in Central America and experienced no problems. I pack light so these were the only shoes I had along. I walked along beaches and through streams and did not experience the separation problems others have had. I found them to be very comfortable. I had always worn hiking shoes on trips but took a risk with these and was really happy with them. No sore feet either. I wear a size 9-2E shoe and found these fit my foot since the bungee cord on the top of the shoe can be loosened. Also, I have experienced a lot of problems with antimicrobial products as I find they don't help at all with the stink from my sweating feet but the material on these Teva's does the job. I walked through ocean water on a hike and the shoes did stink the next day but after rinsing them in fresh water the odor was gone.  I highly recommend but don't buy up all of the size 9's, I may want to buy another pair in a year or so.
