Toning footwear is nothing new, but the EasyTone range by Reebok is leaps and bounds ahead in the style stakes (model Bar Refaeli wears them well). Along with a lightweight design that's perfect for summer, the new shoe boasts superior cushioning. Using a balance pod system invented by a NASA engineer, expect to see your butt toned by 28 per cent along with your hamstrings and calves showing noticeable results.

£65, available nationwide. More information from reebok.com/womens
