Size/Fit Summary: True to size, Regular fit with back adjustability. Designed for a flexible fit, the Original Tall Adjustable Boot mirrors the iconic Original Tall with the addition of an expandable gusset at the back. Perfect for a wider calf, these matte wellies in classic black offer ease of movement and adjust from the traditional tailored Hunter fit to a more relaxed shape when the gusset is fully extended. Handcrafted from natural rubber, the Original Adjustable boot is fully waterproof with a comfortable polyester lining and the signature Hunter Original tread. Hunter recommend that all Hunter boots be worn with socks to protect the wearer's skin from contact with rubber.
