How a girl can quickly (as well as effortlessly and economically) freshen up her work look after a long day in the office, readying herself for a night on the town?

Debenhams may, after all these years, finally have the answer: the 2-in-1 boot.

The unique leather boot – the brainchild of London-based designer Betty Jackson – begins life as the casual Chelsea ankle-high.

In a matter of seconds – and with a little help from a long leather cuff which fastens beneath the foot – it can become a completely different, smarter evening knee-high with buckle detail.

Debenhams 2in1 boots

Available in black and brown, the innovative product costs £120 ($188) and was developed after customer research showed that women wanted a quick and simple solution to shaking up their work look.

Natelle Baddeley, Head of Accessories Design at Debenhams: “This boot is the ultimate choice in footwear for fashion-savvy recessionistas.

“Women are being more and more careful with their cash than before, but still want to invest in great quality and design.

“We wanted to offer our customers that little bit extra, so thought what better than two on-trend, stylish boots for the price of one!”
