Charles Krakoffwrote a review of Merrell Wilderness USA Backpacking Boot - Men's on October 7, 2013
Familiarity: I've used it once or twice and have initial impressions
Fit: True to size
I bought a pair of these, having done extensive online research and persuaded by the rave reviews. I first wore them on a day hike in the White Mountains and apart from a minor hot spot on the ball of one foot, I was very pleased. Then I wore them on a two-day hike on the Long Trail. Day One was fine, no problems. Then, on Day 2, the problems began. I started feeling very sharp pain on the outside of both ankles. It had nothing to do with friction: this was in the bone, just above the malleolus (the bony spur of the ankle). The weird thing was that I could see no obvious pressure point in the boot. I tried loosening them, tightening them , changing socks, putting on moleskin, all to no avail. Finally, I took them off and hiked the remaining 3 miles or so in my Crocs. It is not a problem with the fit, per se. I bought them in a Size 10 and the length and width are appropriate. I do have pretty skinny calves and ankles, and flat feet, but I typically wear Superfeet green insoles to compensate and they normally work fine, and have done in other hiking shoes I have owned. As a result of this experience, I had painful swollen patches on both ankles that lasted well over a week and even now, over a month later, I still have some pain. I wish I could get back the 300 bucks I wasted on these boots, but even more I would like to find a decent alternative. I did notice that many of the through hikers (doing the entire AT) were wearing low-cut boots or even running shoes, and seemed none the worse for wear after 1,500 miles, so I may try that next, using my low-cut Keens or something similar, and keeping my Crocs or Keen sandals with me for backup, just in case.
