New Balance Arch Stability Insoles 3720

Now featuring a fresh, new look! These are the same great quality insoles that you've grown to love and depend on, now with updated packaging and insole appearance.

The New Balance Arch Stability Cushioning Insoles are built for everyday life, athletics, standing, running, walking, and work for those with flat feet, low arches, and neutral arches. These insoles are perfect if you're on your feet all day or for walking, running, or athletics.  Suitable for those seeking a flexible arch support and extreme cushioning for foot pain relief. Ideal for providing arch support, extra shock absorption, and cushioning, the stability insoles provide targeted heel and arch support for increased foot stability.

Features and Benefits:

  • Anti-blister top fabric cover to help keep feet dry and cool and to prevent foot movement 
  • MicroZap® antimicrobial fused into the top fabric cover kills odor-causing bacteria
  • Hytrel® arch plate for superior arch support and cushioning to help relieve arch pain including plantar fasciitis.
  • Orange Abzorb cushioning layers made of Poron to provide extra cushioning in the heel and forefoot while retaining its shape and flexibility versus other forms of cushion (which tend to break down over time)
  • Air flow channels built into the insoles designed to move warm air out and pull cool air in for heat relief
  • Deep heel cup that uses the foot's natural heel padding to assist in providing extra cushion 
  • Ideal for flat feet, low-arched feet, and neutral-arched feet (for those seeking neutral to high arch support, check out the New Balance Supportive Cushioning Insoles)
  • Fits most athletic, casual, dress, hiking shoes, and boots with removable shoe inserts
  • For sizing: If between sizes, order the smaller size (the insoles will fit the stated size and one-half size greater, e.g. Men's 10-10.5)


  • Polyester
  • Micro-Zap antimicrobial and anti-blister top cover

Customer Reviews

  1. Best for me Review by JoeDTrader

    Agree with those who say finding the right insole is a personal matter, and there are many to choose from. For comfort and also as relief from plantar fasciitis these New Balance stability insoles are the best for me! Well worth the cost, which I think is the best on the Internet. (Posted on 3/17/2016)

  2. Just as good as prescription ones Review by SenseiD

    I've had a pair of these New Balance Stability insoles for a few years now and I've found them to be equal to the expensive prescription ones. They've lasted me a few years through moderate use. (Posted on 1/2/2016)

  3. Great Insoles but low durability Review by MattNak

    These NB Stability Insoles (IAS3720) are my favorite insoles. I like em because they're not too thick and they'll fit in any shoes. Super comfy. But they wear out quicker than other insoles. I get holes in them up by my toes. (Posted on 12/1/2015)

  4. Good deal! Review by Cetrev

    I shopped and this was the best price found. A bit expensive still, but the New Balance Stability insoles seem to work, so worth the price. I will order again from this company due to the price and speed of shipping. (Posted on 10/12/2015)
