Women's Crocs Freesail Printed Lined Clog are the perfect shoes for Fall/Winter. I use them to slip on to walk my dog .....especially love them at night when temps drop. Very comfortable and fit me well. I purchased one size up because I knew they were lined. They fit great. I'm sure they would have fit well if I ordered them in my size as well. A little big, in one size up, but not that much of a difference. I wear them around the house for extra warmth as well. All around a nice croc that I'm happy to have in my collection.
If you have flatter feet then running shoes with more cushioning is the way to go. Having extra material to absorb impact on ground strike will translate into more distance and less fatigue. Runners with a more neutral foot type can make selections that are considered more “middle of the road”. Make sure you also check the way that your old shoes wear on the outsole, this can tell you a lot about the way you step.
