The most common activities people use Edge for are basketball, volleyball, squash, racquetball, workouts and dance classes, indoor soccer (futsal), boxing, and floor hockey. It works best on indoor athletic surfaces. Since you can use Edge anywhere you use shoes and on all types of rubber, we encourage you to try it wherever you could use more grip / tackiness!

See all the activities listed in the FAQ above. Whether to improve agility, footwork, and performance or to help minimize slip-ups and injuries, Edge is relevant for anyone that partakes in indoor athletic activity, whether it's recreational, competitive, intramural, or at the High School, College, and Pro levels.

Edge's effect is most noticeable on smooth hard surfaces like hardwood, tile, or vinyl flooring, but you can use Edge anywhere you use shoes.

Yes, Edge helps you improve your footing and grip, even on suboptimal indoor athletic surfaces like dusty courts.

Edge has been tested for over 2 years on dozens of shoes. These shoes are of a variety of brands, from different years and levels of wear, and were tested on multiple surfaces. In controlled lab testing, Edge increases the friction coefficient (grip) of rubber soles by 25% on average.

For Men and Women's size 7-12 shoes, it is recommended that you spray 3-5 sprays on each shoe, coating every inch of the sole evenly.

One application will provide you with enhanced grip for an entire session of activity. Since Edge usually dries in under a minute, some users re-apply throughout each session to further maximize their sneaker grip. Your soles will maintain more and more grippiness as you continue using Edge over several sessions.

Each bottle contains 2 fluid ounces of Edge's breakthrough formula and will last around 50 sessions. For example, at three sessions per week a bottle will last you about 4 months.

Edge interacts with the rubber in your soles to create a softer, grippier material without breaking down or removing the surface. We have tested Edge on several pairs of sneakers for over two years straight and longevity has been unaffected. In fact, Edge can help you increase the longevity of your sneakers because your soles will be viable for longer. And don't worry, if some of it happens to land on the body of your shoe, that's totally fine too.

We believe we have a big responsibility to keep all our customers and our environment safe. We have spent over 2 years working through hundreds of versions of the formula, in close contact with the EPA, to create a safe and effective formula. The final result is a product we feel great about using anywhere, anytime, around all of our loved ones.

Edge was designed to be legal under NBA and NCAA guidelines and should be legal in all local leagues. We can't know for sure what your league's regulations are, but Edge complies with NCAA guidelines!
