I'd been looking for about 3 years for a replacement to my winter boots. I have larger calves and find that a man's boot works pretty well for me but finding one that had zippers for easy access and a low heel with good tread and not too heavily lined was very difficult. In addition, I have custom orthotics so I needed space for them too. I finally found what I needed in this boot. I wear my boots outside through Minnesota snow and ice but also like something not too warm so I can wear it all day in the office too; these work well for my purposes. I ended up ordering an extra wide size when a wide (or maybe even regular since it was men's) might have worked because that is what was in stock at the time. I may need to add an extra cushion to make them feel a little less 'sloppy' but I think they will stand the test of time and be with me for quite a while.
