I've worn out 3 pairs of the 5.10 Tennie Guide's over the last 10 years. I only wish I had more. They are fantastic. I keep the laces loose when walking around town, but when I'm in the Teton's on some approach, I tighten them up for crazy grippy friction. I've climbed up to 5.8 in these things and they feel so comfy. If your looking for long lasting get the leather over the canvas.
