It can also help with joint pain in the knees and pain in the lower back.


What Should I Look for in the Best Insoles for Military Boots?

You want the insoles to make your combat boots more comfortable and give your feet support. Some of the things to look for include:

  • Arch support: Insoles generally supply some support for your arches, in a rigid or semi-rigid form. They can contribute to keeping your feet stable.
  • Heel support: This will help hold your foot in the correct position and provide some support to your ankles.
  • Cushioning: This provides comfort for your feet by helping absorb the shock that is caused by normal walking and running. It’s usually provided by gel or foam incorporated into the insole. Some can be molded to fit your feet.
  • Antimicrobial properties: These help control the bacteria which cause foot odor. Some will also have wicking properties which take the moisture away from your feet, allowing them to breathe and stay dry.
