I would get aching hips after walking more than 8 miles or standing around all day, because my arches were not supported, this solved the problem, 5 stars.
I have the green ones and decided to get the orange ones. They provide excellent support. Put them in my boots and walked eleven miles in comfort. Great!
I wouldn't say they were good value, although ShoeInsoles.co.uk offered the best price. But they do seem to make a difference in everyday shoes and hiking boots. I tried in proper cycling shoes and they were awful, I'm guessing they have a preshaped sole.
Ordered these to combat plantar faciitis. They have worked for me. Easy to fit and comfortable to wear, and have eased my foot pain considerably. Worth the expense.
