Teva Womens Boots 70%-80% off on Amazon. I’m told these are very comfortable and are geared also towards outdoor. They are suppose to be very very warm!
Amazon offers free shipping (or free 2 day Prime, if you have it). I can also attest amazon makes returns for shoes and apparel very easy; you just print out the label and use the same box with free return shipping, so there’s no risk to trying additional styles and sizes! Links below.
