I'd been almost crawling around with pain in the ball of my right foot and the joint below the big toe, never realised feet could be so painful. If this is you right now, add them to your basket and get delivery underway, you can always come back and read this after! Researched on the internet and found it was most likely to be a fallen arch. A bit more research turned up these insoles and I thought for this price it was well worth a try. Arrived within a couple of days and I put them straight into my shoes. You really need to wear both even if only one foot seems to be affected, and they feel very odd to start with. However, after just 2 days my foot felt massively better and after a week I was able to walk the dog again. I got a second pair so that I don't have to keep swapping them between work shoes and trainers, they have been brilliant. They don't fit all my shoes though and I had to buy a slightly bigger pair of walking shoes (take the insoles with you to buy shoes!) Now after 4 weeks of continuous wear I have forgotten I'm wearing them, anything else feels odd.
