Size/Fit Summary: True to size, Regular fit. Take a leap into colder weather with the new Insulated Play Boot. Technically advanced with a thermal insulated sole and lining, these boots can be worn in temperatures as low as -5°C. Simplifying the iconic design of the Original Boot, the Play Mid-Height Insulated Boot offers a strong and flexible design with a flatter platform sole and angled block heel for maximum comfort. 100% waterproof with an added vibrant contrast lining, this stylish black mid-height boot is ideal for cold wintery days out. We recommend that all Hunter boots be worn with socks to protect the wearer's skin from contact with rubber.
