I am going on a trip where I will be hiking some every day for a week, so I thought I would get a new pair of boots. I picked out some that I saw in a 2BigFeet email but they only went up to size 17M. As those of us with big feet know, fit and comfort depends on the style, manufacturer, etc., so you are never positive that the pair of shoes or boots you pick out will fit well. The first pair (Columbia) felt a little tight, so I looked and found a similar Dunham boot that went up to size 18M. A little more expensive, but as 'big feet' people know, you will pay extra for a good fit. So I ordered the second pair (size 18M) so I could try both on (in my home) and compare. The confidence that I have in 2BigFeet's easy and hassle-free return policy gave me the confidence to buy 2 pair, so I could pick the best fit for me! Nothing against the Columbia boots at all, but the Dunham's gave me a little more room in the toe, so I'm returning the Columbia boots today! Thanks 2BigFeet.com for catering to men with BIG FEET! (PS - I've referred a woman or two to your website, but the feedback I get is that there is not much to choose from. So you might be missing out on another market!)
