I have been using these insoles in my New Balance trail runners. I have no idea the exact mileage but I’ve worn them day hiking and bike riding mostly, but have worn them on several other occasions. I know I have worn them at least an average of three days a week and often all day. I’ll be the first to admit, thinking of something useful to say about a product like this is difficult. They were very comfortable, but still, you put them in a pair of shoes and there is really not that much difference in how the shoe feels before or after, unless the old insoles were worn out. I guess the fact that most of the time I did not even think about them when wearing them is a good thing. To read the rest of the update along with the entire review please click here.
