I bought these for my granddaughter but I also have a pair. They are well made and quite comfortable. Stick to your size, if you wear a full size they may be a little tight but will stretch when worn. I would go up to the next full size if you are a half size. No, there isn't really arch support, but they are as comfortable as a pair of good slippers and so warm! Don't forget to spray them with a good water repellent and you'll be fine!
