I have used the Five Tennies on 2 long alpine approaches (about 5 miles each way) and the stitching is already beginning to fall apart. I've had them about a month and I feel that they will only last me one more month. I am not confident in the durability of these and will not be taking them up any big walls.
The sticky rubber is great. They also get me up cracks can edge about as good as you an expect from an approach shoe.
Easy to Climb in
Lack of haul loop (big deal, use the laces)
Lack of durability
