Girls Aloud keep their shoes on with elastic bands.
The 'No Good Advice' hitmakers - Kimberley Walsh, Cheryl Cole, Sarah Harding, Nicola Roberts and Nadine Coyle - worry about losing their footwear when performing tricky dance routines on stage, so have learned to secure them to prevent accidents.
Kimberley revealed: "My best kept fashion secret is that when Girls Aloud are on tour we have see-through elastic bands that wrap around our feet so that our shoes don't fall off while dancing."
Kimberley's favourite fashion purchases are shoes and she is particularly pleased that she and her bandmate Nicola take the same size as they can swap.
She added: "Nicola has the most interesting and extravagant wardrobe. She also has a really good shoe collection. We're both a size five, so I know they'd all fit me."
