But rather than being what one highly revered women?s health & beauty reporter quoted as 'the most cost-effective boon for cellulite-sufferers ever', our more manly FitFlop model is made to help sporty sorts with warm up/cool down, and those with old injuries, arthritis, or aching joints (or bad backs) walk around without feeling any pain.

Engineered by Dr Dave Cook, a leading UK biomechanist, FitFlops feature a multi-density midsole to maximize muscle-load while you?re moving, while minimizing the joint force you feel. With a firm heel strike to reduce shock (by 36% in every step), a soft midstep section to add a wobbleboard workout (12-15% more muscle load in every step) and a harder toe-off section for speed - the Dass is weekend warrior relief a worn-out guy can simply wear.

Dr Philip Graham-Smith, a consultant biomechanist for UK Athletics, and head of the directorate of sport at Salford University says: 'We're currently investigating the pain-reducing phenomena that the FitFlops have been reported to have. Our belief is that walking in FitFlops promotes better force alignment and a biomechanically correct gait, reducing stress on the knee. For athletes or people recovering from or dealing with a variety of old injuries, the relief felt could be significant.'

Just a reminder, though, gentlemen: They only work when you walk in them
