Win one of four Medisana foot and bath spas

After a hard do in your heels, nothing beats a nice relaxaing footspa. We've learned that the hard way here at The Independent, and we'd hate for that to happen to you, so we've got our hands on four expensive footspas - and four more equally pricey bath spas - courtesy of the nice folks at Medisana, and we'd like for you guys to win them.

That's not all! Because we care so much about your health, we'll also throw in a Medisana MediTouch blood sugar monitor, designed to make measuring your blood glucose levels an easy and discrete task, so you can keep an eye out for diabetes to boot.

All you need to do to enter is answer the question below, and we'll pick four winners at random.

This competition closes on Monday 8 August. The Independent's usual competition rules apply.
