Fit foot well, but the ankle above will take a good breaking in to be comfortable. The split on the top comes lower than my last pair, and when I walk it knocks back to my leg. As the leather softens from wear that will improve. I suppose I could tuck my jeans in the boots, but that's not how I wear them. I bought the brand and size because I had a pair of the same brand already. I wouldn't have bought them if I'd been able to try them on first, because I can see they won't be as comfortable as the last pair. If I'd had very large ankles or calves this might have actually been a plus for the extra room.The color and quality are excellent. I was impressed with the reinforced toe, and it didn't change the comfort if the fit for my foot. I was very pleased with the fit from the ankle down.I have owned this boot before it has great look and very durable. I use for work and on the farm it is comfortable I wear everyday.These boots are comfortable and they fit well. But barely 2 months in and the sole is coming apart and I can't return themThe right boot last long about a month, it start falling a part. The sole star peeling off and the leather part turn really soft, just like cardboard. Really bad quality2months old and the bottom of the boot is ripping off. Waste of moneyAfter 20 yrs with Justin's 476# series with steel toe I never had a problem every pair fit like a glove. I was having problems with availiblilty of the 476# series boots in my size so I decided to try the 4643 and the left boot fit a little tight across the top of the foot which they ussually do until break-in, however the right boot I could not even get my foot in beause of how tight the curve was, the differance can been seen with the boots placed side by side. I streached the boots overnight and am able to get my foot in the boot now, but it will require alot more streaching as it is too tight still, and I could have just gotten a bad boot in the pair however I find it unacceptable from a company like Justin. When did Justin start selling Made in China boots?Defective, left boot came unglued on first use.Very front under toesBought these for my boyfriend to wear to work and he loves them. He loves the colors as well as how they feel. He works 12 hour days all while on his feet and he never complains that his feet are hurting. His only concern was that the insoles started slipping out not long after he got them but we just bought some more insoles for them.
