Sidas has long been a leader in performance foot care, and their non-slip 3Feet Trail Insoles continue to innovate and will cushion and support you from buttery smooth single track to the roughest off-trail tech. Made to last through your training blocks and ultra-distance races and structured for the uneven surfaces encountered once off the security of sidewalks. The Low, Medium, and High arch heights will accommodate most arch lengths, foot shapes, and heel widths for a near-custom fit. A generous rubber pad under the ball of the foot keeps the insole in place, which, in turn, reduces rubbing and discomfort, making long days out more enjoyable. The 3Feet Trail Insoles offer out-of-the-box comfort and long-term support, only bettered by custom work.

  • Sidas Grip Tech keeps insoles and feet in place.
  • High, Mid, and Low-arch fit most and alleviate the need for customs.
  • Structured to stand up to the wear and tear of off-trail travel.
  • Replacing flimsy factory insoles has never made more sense or been more effortless.

Update 2025: The new V2 version features a new Dynatine forefoot pad, which offers better durability with a smidge of extra propulsion as well, while being slightly lighter.

I purchased these for my Norda 001a shoes to get some more arch support for my high arches and narrow feet. After a few runs they work great. They didn't impact the volume of the shoe dramatically or change the fit. Easy to cut to fit.
A tip for sizing: the brand's size chart does not specify that the shoe size range listed is a men's size. I originally ordered a medium and they were way too big. Dropping one size down was perfect, and Skyrun made the return easy peasy!
