These boots are great for a person that needs a 2E or above wide shoe. These Lugz run wider than the normal boot so if your a 2E width the D width will do. If you find one 2E then you'll have plenty of space for a thermal sock. The downfall to these boots I've notice is if your using them for work expect to replace them in 6-9 months. The inner sole will have to be replace more often as well. They have a workforce model of these which the sole will last a bit longer but its hard to find. I worked in a casino for 2 years and went through 4 pairs just walking and 8 inner soles. Figure if your job has you on your feet for more than 6 hours a day and your work week is five days on them you'll burn right though these a lot better than any walking sneaker I bought. I enjoy these a lot more since I have wide feet and Timberlands are too pricey for my size. I'm wear a size 8 1/2 2E if I were to buy a Tim I would need to get a 9 1/2 Wide (rare) which ranges in the high $160-$200 mark but still need to take to a leather streacher to fit right. I've been lucky to find these under $50-$40 each time I need a new pair. Which makes them a bargin even having to purchase inner soles. Plus, I'm able to buy the right size that fits every time. Another benefit is that they make me an inch taller and help my posture.
