Let me start by saying I have worn many different boots over the years and for the last 6 years Justin have been my go to workboot. That being said this is the first time buying the x5 boots. Normally I bought the 120$ boot steel toe. So if you have never owned justins boots know they run big in size, to put in perspective I wear a 11 1/2- 12 in shoes but in my Justin work boots I wear 9 1/2 comfortably. The x5 are by far a very well made boot, didn't notice any flaws in the boots I received. They are very comfortable, putting the boot on the first time already has the comfort of a 3 week broken in boot. After wearing the first day at work, I had no foot fatigue so little to no brake in required on these. I will say that because of the rubber reinforced heel being so stiff at first, that could cause issues for some. On that point the upper boot holds shape nicely and cause no rubbing irritation on my calves. Over all so far I'm very pleased with the x5 boots, it was the first time I put that much money into a pair of work boots, but I can gladly say after wearing these I will again, in conclusion, WORTH IT!!!!
