After 15 trips to the mountain the Darko's definitely show more then a little wear and tear. On both boots the inside to the metal lace hooks is beginning to wear through the tongue. I have avoided further wear by putting a piece of duck tape over the metal and putting vaseline on the leather.
The boot does have articulated cuffs which allow the boot to flex forward with relative ease. At the same time it reduces pressure and hot spots on the top of the foot. As others have mentioned, the boot runs wide in the toe box (fits my bunions) and snug in the heel. They are very comfortable to walk around in. When I bought these, the salesperson really sold me on how soft the sole was, almost like a temperpudic bed, keep in mind when it is cold this material gets hard. The liners are removable and heat moldable. Unfortunately, the liner fabric is already coming unglued in one of the boots. Another concern for the future is the stitching on top of the toe is at a spot that get excessive wear. Again, I plan on applying ducktape on my next trip to the mountain.
Overall, I would recommend these boots for the fit and comfort. Just plan on getting one season (50+ 8 hour days) out of them.
