The Heritage Twist collection from Swift & Co is the subject of two patents pending. The first is for our interlocking sole design, featuring a shock-absorbent inner sole that integrates with the midsole, offering unrivalled comfort and eradicating 'slip'. Our second revolutionary innovation concerns the bespoke machinery used to make Heritage Twist. Each shoe starts construction 'inside-out', then inverted before finishing - a unique approach, truly connecting the sole and upper. Tough, durable stitching reduces the use of environmentally harmful adhesives.
