Enjoy flexible payments with Klarna

Finding the perfect leggings, trainers or fitness support accessories can be tough. Why not try before you buy with Klarna? This gives you the option to have the products you’re interested in sent to you without paying, giving you 14 days to decide if they’re for you or not. If you decide you don’t like an item, send it back within the 30 day period and you won’t have to pay a penny.

This is also great if you need some new gear but are waiting for payday. Get the items you’ve had your eye on now, pay for what you want to keep later and return the rest for free. So long as you pay before the 30-day deadline there’s no interest or hidden fees, making it an easier, more flexible way to shop on a budget. To pay using Klarna, simply click ‘pay later with Klarna’ at checkout and make an account for free.
