Kelly Brook's EasyTone Reebok mentors unfit for purpose: Watchdogs have banned adverts for trainers that promised ‘better legs and a better bum with every step’. After studying the claims in two promotions for Reebok’s EasyTone shoes, the Advertising Standards Authority concluded they were ‘misleading’. The adverts claimed the curved soles of the trainers made the legs and bottom work harder to keep the body stable while running or walking.

On the TV commercial, the voiceover stated: ‘Helps tone legs and bum more than regular trainers. 'Better legs and a better bum with every step.’The magazine advertisement promised: ‘Get up to 28 per cent more of a workout for your bum. And up to 11 per cent more for your hamstrings and calves.’But the ASA said: ‘Because we considered that we had not seen robust, scientific evidence to support the efficacy claims made in the magazine ad or the TV ad, we concluded that the claims had not been substantiated and were misleading.’
