Samurai Insoles Sumos are designed to comfortably support your arch and help correct the effects of foot overpronation—a common cause of discomfort in the feet, legs, and even lower back.

That built-in, springy support can help relieve symptoms associated with:

• Plantar Fasciitis

• Flat Feet

• Heel Spurs

• Shin Splints

• Ball of the Foot Pains

• Knee Pain

• Tired, achy legs from long days on your feet

By improving alignment and reducing strain on your arches, Sumos help your feet move the way they’re meant to—so you feel better with every step.

Yes—Samurai Insoles Sumos are built with extra-thick cushioning, so they work best in roomier shoes that have a removable factory insole.

Think work boots, hiking boots, athletic sneakers, or casual comfort shoes with plenty of interior space.

If your shoes run snug, our Original Samurai Insoles may be a better fit.

Usually pretty quickly—just 7 to 14 days!

We recommend starting slow: wear your Samurai Insoles Sumos for about an hour on the first day, then remove them.

Each day after that, add one more hour of wear until you’re comfortably hitting 8 consecutive hours.

If your feet feel tired or sore at any point (it’s rare, but it happens), just take them out, give your feet a break, and try again the next day for the same amount of time—then keep building from there.

Small steps = big relief.

Samurai Insoles Sumos are built tough—and we stand behind them.

They’re warrantied against manufacturing defects for 60 days from your purchase date.

With normal daily use, many customers enjoy months of lasting support and comfort.

Of course, like anything you wear daily, heavy athletic use (think running or high-intensity sports) may wear them down a little faster than casual everyday use.

Bottom line?

They’re designed to go the distance—and to keep your feet feeling better, longer.
