Depending on your level of activity and unique biomechanics, the answer lies somewhere between probably and absolutely. Here's why:

Manufacturers' insoles wear thin, fast
Problem: Insoles that come with running and other athletic shoes lose what little shock-absorption properties they have around 50 miles, leaving you susceptible to pain and injury. Replacing them with a high-performance insole is the easiest, cheapest way to protect against injury and alleviate impact-related pain, jarring and fatigue.
Insole Solution: For linear sports such as running and walking, try Ultra Graphite Arch™, Ultra Sole™, Women's Ultra Sole™ or SorboElite™. For lateral sports such as tennis or basketball, try SorboAir®.

You can't defy the laws of gravity
Problem: Feet absorb about 300 tons of force per mile. According to The American Journal of Medicine and Sports, recreational runners have a 37-56% chance per year of sustaining an injury. Sorbothane insoles reduce your risk for injury by absorbing up to 94.7% of impact shock.
Insole Solution: For runners, we suggest Ultra Graphite Arch™ or SorboElite™. And SorboAir® for post-workout comfort.

To be human is to be flawed
Problem: We're each born with certain biomechanical idiosyncracies. It shows in the way we move. And on occasion, it hurts in the way we move. Insoles can help to properly align muscles, bones, tendons and ligaments, alleviating the stress and strain innate flaws put on our bodies every day.
Insole Solution: Ultra Graphite Arch™, SorboElite™, Sorbothane® Full Rigid Arch™, and Sorbothane® 3/4 Rigid Arch properly align feet and everything connected to them.

Too much roll takes a toll
Problem: Most people overpronate, which means their feet roll excessively inward with each step. This twists the foot, shin and knee and can cause pain in all those areas. Insoles with arch support provide the kind of motion control that can remedy painful conditions caused by pronation.
Insole Solution: Ultra Graphite Arch™, SorboElite™, Sorbothane® Full Rigid Arch™, and Sorbothane® 3/4 Rigid Arch provide the firmest arch support.

Shoes can rub you the wrong way
Problem: An insole can make a shoe fit better. If shoes are even slightly too big, your feet will move around in the shoe causing blisters.
Insole Solution: Ultra Graphite Arch™, Ultra Sole™, Women's Ultra Sole™, SorboAir®, Sorbothane® Full Rigid Arch™, Sorbothane® 3/4 Rigid Arch, SorboElite™, and Sorbothane® Heel Pad can all help in this area.

Have you caught a whiff of your shoes?
Problem: There are 250,000 sweat glands in each foot that excrete about one cup of perspiration a day. No wonder shoes stink. Unlike shoe manufacturers' insoles, Sorbothane's contain antifungal properties to keep feet dry and healthy.
Insole Solution: Ultra Graphite Arch™, Ultra Sole™, Women's Ultra Sole™, SorboAir®, Sorbothane® Full Rigid Arch™, Sorbothane® 3/4 Rigid Arch, SorboElite™, Sorbothane® Heel Pad are all antifungal.
