Size/Fit Summary: Slightly larger size, Regular fit. If you are in-between sizes, it is recommended to size down. Note: The neoprene upper is not waterproof. The Women’s PLAY Neoprene Boot is a new addition to our lightweight footwear family. This silhouette combines our signature natural, vegan rubber from our PLAY collection with a water-resistant, insulating and flexible neoprene for ease of movement. This matte dark green boot features a 100% recycled polyester lining and insole. We recommend that all Hunter Play boots be worn with Hunter Play socks to protect the wearer's skin from contact with rubber.
