I'm a shift manager for a high end coffee shop at a very high volume store. I end up walking about 5 miles a day during my 8 hour shift. Other insoles would barely last me a month before I needed new ones and it was taking a toll on my knees.
Since purchasing the M75 in August, I have noticed a marked difference in how much more energy I have at the end of my shift and my calves hurt significantly less. I love recommending these to any of my employees and to anyone who works on their feet. I'm going to be a life long customer
