The 3Feet Outdoor footbeds feature a grippy top sheet which can help hold your feet securely in your footwear. These pre formed supportive arch foot beds have a low to medium arch shape so they make a great choice for people who want to improve the support of their footwear. These foot beds have been designed with a foam top sheet and gel shock absorber under the heel, for an amazing cushioned feel, firm enough to give support but still very comfortable. They are a great choice for people wanting to soften the sole of their shoes or boots.
