Looking for a great pair of knee boots? Keep things simple…with the Sumi. Clean. Classic. In smooth leather at the front, with matching stretch faux-leather at the back for a sleek fit. An inside partial zip gives easy on/off. And they’re on our ergonomic pressure-diffusing SupercomFF™ midsoles for superb all-day cushion and comfort. Equally good with a smart dress or over skinnies, they’ll be one of the most versatile pieces in your wardrobe. Sizing note: These boots are a slim to average fit around the calf/leg. The circumference around the top line (when boots are unstretched/not on the leg) is: UK size 3 – 366mm, UK size 4 – 374mm, UK size 5 – 382mm, UK size 6 – 390mm, UK size 7 – 398mm, UK size 8 – 408mm, UK size 9 – 416mm. The faux-leather back panel means the boots can stretch a little beyond these measurements to accommodate the leg when on.
