These fit really well. I read the reviews after I purchased and was worried my ankles would have a problem. I'm 7 months pregnant and currently have kankles. For the most part though, it's great! and when they're really swollen, I just unzip the zipper a little bit to give myself some room. I wouldn't see any issues with these though if your feet aren't swollen.
They're really supportive and are nice to walk around in, however, sometimes it does feel like my toes get a bit squished. that's the only reason I knocked it down to 4 stars, hopefully i'll break them in enough to where it doesn't bother me anymore. Would still recommend.
