How RunSizer works
We check prices and stock across the UK's top running retailers so you don't have to visit six websites to find your size.
The three steps
Search for your shoe
Use the search bar to find any shoe in our catalogue: Nike, Hoka, Asics, Brooks, New Balance, On Running, Saucony, Adidas, and more. You can also browse by brand or use our Your Sizer quiz if you are not sure what you are looking for.
Pick your size
Select your UK size on the product page and we instantly filter results to show only retailers who have that size in stock right now.
Buy at the best price
Retailers are sorted lowest price first. Click through to buy directly on the retailer's own website. We never hold your payment details or process any transactions.
What we do and don't control
Prices
Updated regularly but prices can change at any time. Always confirm the final price on the retailer's site before purchasing.
Stock
Stock levels reflect what retailers report. A shoe marked in stock may sell out before you complete checkout. This is outside our control.
Delivery & returns
Delivery times, costs, and returns policies are set entirely by each retailer. Check their site for details before buying.
RunSizer is a price comparison tool. We are not a retailer and we do not sell shoes directly. All purchases are made on the retailer's own website under their own terms and conditions.
How we make money
RunSizer is free to use. When you click through from our site and make a purchase, we may earn a small affiliate commission from the retailer. This is sometimes called affiliate marketing and it is how most price comparison sites work.
Affiliate relationships never influence how we rank results or which shoes we recommend. Prices are always sorted lowest first, regardless of which retailer pays the highest commission. Our guides and Your Sizer quiz are written independently with no paid placement.
The commission comes from the retailer's margin and does not increase the price you pay. You will pay exactly the same price whether you clicked from RunSizer or went directly to the retailer.
Your Sizer
Not sure which shoe is right for you? Your Sizer is a short quiz that asks about your running goals, experience, and budget, then recommends the best shoe for your needs. It takes about two minutes and is completely free.
