I have worn Merrell Moab Ventilators for years. They are comfortable and never give me blisters. The problem is that the Vibram soles are dangerously slick and they always have been. After nearly breaking my arm on a rainy backpacking trip, I've had enough. Tennis shoes would provide better grip than the Moabs. Can anyone suggest alternative shoes that are similar, but with better traction? I am a size 14 and don't have the ability to try on a lot of different shoes at local outfitters. Any suggestions would be appreciated!
