I suffer with unsightly ankle edema and have a difficult time finding shoes, sneakers and/or boots to accommodate my swelling ankles. I live in an area with a rainy season and having rain boots that fit is something I thought would never happen.  I was thrilled to find these.  I love the colors, they match almost everything I own.  I was concerned because I've never purchased an extra wide shoe/boot before (my feet don't swell as badly as my ankles).  However, if you share these concerns, let me put them to rest.  These are the most comfortable rain boots I've purchased to date.  They are easy to don and doff, and my foot doesn't slide around inside the boot, nor are they pinched.  There's plenty of room around the ankle, and just above, for my most severe swollen days.  I did add a very thin insole, one with an arch, for added comfort (on the plus side, adding the insole did not make the boot too tight).
I'm not a fan of polka dots (the only other model in the ankle height) but I might just buy them ( it's a habit of mine...find a shoe that fits and buy every color, lol).  I wish this company made high top sneakers and leather booties!!!
