Without doubt Amazon have the most extensive range of large size shoes available for both men and women online. They feature a broad range of different retailers stocking pretty much any style or type of shoe you could possibly imagine.
The only minor drawback is they don’t tend to feature the discounts that specialist retailers sometimes offer with their promotions. Just because it’s Amazon doesn’t mean it’s necessarily the best value so shop around. Many of the other retailers featured on this site don’t sell on Amazon so be sure to check out their websites too.
