Teva Omnium sandals (made for river rafting?) work good for me. I use MKS Lambda flat pedals, and the Teva have good grip in wet and dry weather. I apply shoe goo on the bottom sole once a month or so in a few places where the pedals dig in or scrape into the shoe. I have used these for over 2 years. I commute every work day about 25 miles round trip. They are also fine on longer weekend rides (40-50 miles).
