I am 5'5", 115 lbs, 13" calves, 8 1/2 shoe.
Based on the previous reviews that these boots run small, I ordered the plum a half size up in  9's at the lowest price, $23.98, before they went out of stock and they look great. Elsewhere, they go for $54. These boots are of nice quality and very bright. However, the brightness will vary depending on how much the fabric was stretched when they laminated the fabric on inside. More stretch means a little less bright, but not enough to worry about. Beware if you have a very high arch, they are tight right at the top middle of the foot. I have room to tuck in my skinny jeans. The top of the boot edge does hit the calf when driving, so this feels a little weird, but nothing you can't get used to.

Then I ordered myself and my daughter each a pair in the navy. They are as bright as the photo. When I went to wear them in the rain here, I noticed a large permanent rip or pull in the fabric at the heel of the right boot, you could see my socked heel through the clear laminate, so I took one star off for this. I got Amazon to send out a new pair express due to the manufacturer's defect. They arrived 2 days later and they look fine.

Great boot, but order a half or full size up; and they're not for those with a really high arch or who have really large calves and want to tuck in jeans too.
