Zappos.com is a wonderful site with great customer service, but I personally find it difficult to find what I’m looking for on the site.
This site lists some heavy winter boots that are more on the fashionable side.
I don’t know what your style is, but Uggs are more on trend than they are fashionable. They are quite expensive and the trend is likely to end soon, so I don’t personally recommend making the investment.
I love Piperlime.com. It’s a a general fashion site, but it is mostly a fashion shoe source, and they have a great selection for different tastes, from trendy to classic. I don’t know what your budget is, but their shoes are, overall, on the more expensive side. However, they are also top quality. I have tried to list a range of their more affordable shoes that might fit your style and needs below.
I found these boots on Piperlime which I thought might fit your needs and your fashion sense, and they’re not too expensive.
These also appear that they are warm/comfortable and can handle the elements, but are stylish at the same time.
Boots like these are also in style right now, but seem warm and durable.
If you’re not too fond of any of these suggestions or want to look at more on the site, go to this page and do a ctrl + f search for the phrase “hiker booties.” There are plenty of options that might fit what you want from the “Hiker Booties” section down to the bottom of the page.
