This is my third pair of Alpha Force boots from Rocky, but my first in the 6" (the other's were 8"). The folds on either side of the tongue make lacing this boot tight uncomfortable for me because they're situated near the bony parts of the lower foot/upper ankle. The 8" boots have these folds another 2" higher on the ankle where there is more muscle than bone. There is plenty of room on the ankle of this boot to run that piece of material up another inch or so, putting it into more "meaty" territory and resolving the discomfort. Otherwise, this boot is solid, Rocky makes some very comfortable boots and they tend to last. The waterproof claims hold up well in actual use too, too bad these boots, on my feet and in this size were painful to wear. Your mileage may vary based on the composition of your foot and the size of boot you wear. Thankfully, Amazon has solid return policies.
