I found these shoes on sale at the local Cabellas and decided to give them a try. I love how they fit my feet! I have an extra wide foot and the shoe fabric stretched accordingly to accomodate (I am size 6.5 D-E). I brought these to costa rica for two days of whitewater rafting, a day of canyoning and more recently on some kayaking adventures. As great as the fit is however I found these shoes to not provide much traction on wet rocks. Granted, most shoes fail in this category but as water shoes I expected the keens to perform better. I would have been better off in sneakers. I wouldn't recommend these if you will be moving around on, hiking or climbing wet rocks and need good traction.
