Testimonials

"I really like that they don't require much space in my footwear. They attached easily, worked well, and haven't needed to be replaced yet. The patch kept my foot from rubbing uncomfortably and becoming irritated."

Independent Field Test Groups

BackpackGearTestA group of experienced backpackers will be evaluating ENGO during the next year. They will be writing and discussing ENGO’s performance against blisters and other skin irritation on the Back Pack Gear Test website. Follow along with their creative and educational experiences!

Sponsored Studies

University of Missouri has performed coefficient of friction testing on a variety of sock materials. Read about how moisture or sweaty socks play a major factor in causing blisters at Startribune.com.

Minnesota State University, Mankato and Minnesota State University, Moorhead are currently studying the effectiveness of using a friction reducing product in decreasing treatment and discomfort time for foot blisters on male and female athletes. The study should conclude December 2006 at which time an analysis will be completed and findings submitted to The Journal of Athletic Training. Stay tuned for the results.
