Chillbies sizing are based off a men's US sizing chart. If you typically wear a half size, it's recommended you size down. For example, if you wear a size 9.5, size down to a 9. If you normally wear women's shoes, it's recommended you size down two US women's sizes. For example, if you wear a women's 7, size down to a 5. Waterproof Slip Resistant Performs well in snow and rain as well as hydrochloric acid, ammonium hydroxide and all motor oil environments
