Upon initial fitting, (compared to most boots I’ve worn in my 21-yr military career) these “wide” boots were extremely snug in the tow box area.These boots, LIKE ANY BOOTS, have a break-in period. It took about two weeks of constant wear for proper heel-imbedding and flex-point break-in. The tow-box widened-out, as the flex-point broke-in. I swapped between lacing techniques to re-distribute uncomfortable top-side pressure and increase comfort during the process.Bear all of this in mind, if your initial fit isn't immediately comfortable.These have become exceptionally comfortable with time and the extended lacing (to the toe) has proven to be incredibly functional. Pretty close to perfect.Some things to point out to those wondering:1. Don't expect much tactile feel or flex from the sole. These are purpose-built "hiking boots", not shoes.2. The sole is not a "zero drop", if that matters.3. Yes, they're very light.Some tips to increase your comfort, if you buy these, or have already bought these:1. Remove the rubber Tactical Research label from the tongue. Where it's positioned, it sits directly behind the knot, when you tie them up. It can cause some pretty uncomfortable pressure at the front of the ankle. Removing it increases comfort around the ankle immensely.2. Re-lace them in a way that’s comfortable for you. There's a few different boot lacing techniques you'll find, if you search the topic. Re-lacing is practical for redistributing tension across the top of your foot for different arch and foot types. It can make a huge difference in break-in and overall comfort.
