Michael W.wrote a review of La Sportiva Synthesis Mid GTX Hiking Boot - Men's on August 19, 2016
Familiarity: I've used it several times
Fit: True to size
Are you kidding me?! That was my reaction when I got home today after putting in miles in 103 degree heat. Pulled the boots off and my socks were dry as a bone! NO SWEAT whatsoever, this with a Gore-Tex liner? In case you are wondering, I wear the Smartwool PhD Run Elite socks. I have yet to test out water permeability, but that will come soon enough here in Portland. Now to the comfort, UNBELIEVABLY COMFORTABLE! In fact, the most comfortable boot I have ever had the pleasure of putting on my feet. And they were comfortable immediately. The boot hugs EVENLY across the top of the foot as you walk, without a single pressure point or hot spot on either foot. The boot tensions very evenly around the entire foot. This is so rare to find in a boot. The insole and the boot itself really works its magic in shock absorption with every step, and just today I was forced to run flat out for about a 1/4 mile, PURE JOY. next, weight, these boots are FEATHER LIGHT, and they feel that way, really easy on the legs and feet after miles and miles. Now, onto the what La Sportiva terms as their brake system. Let me tell you, this is not ad hyperbole, this system WORKS. The traction is the best traction I have ever gotten out of a boot. Period. So, all in all, this boot deserves 5 stars, wish I could give it more! I sure hope La Sportiva does not discontinue this boot, I am thinking of buying another pair just in case. For sizing, I find them standard, I had to go up just a half size from my walking shoe size. Plenty of room in the toe box, and I have wide feet. I am also a huge fan of speed laces, and here the Synthesis boot does not disappoint. So, there you go...get a pair and put a real smile on your face!
