Let me save you the time and money I wasted.
Over the past 3 years, I've tried £145 Brooks running shoes, £169 custom orthotics, £89 memory foam sneakers, those ugly Skechers my mum recommended, two different "orthopedic" brands, some £29 Amazon shoes with 5-star reviews, and finally, these sneakers everyone in my walking group kept talking about.
Six failures. One winner. Here's the difference. And what I wish someone had told me before I spent £825.
