ProKinetics UltraThin Insoles

Important Note: Due to limited inventory, the Ultra Thin Insoles with 3.5mm correction are not included in the JulySale25 and are available only at regular price. Good news! Our Ultrathin Insoles with 6mm correction are fully stocked and available at special JulySale25 prices — so you can still enjoy premium support and great savings!

The most versatile of our insoles can be used in any style shoes to improve your gait and posture and eliminate body pain. The original Posture Control Insoles have been available for over 20 years and are worn by hundreds of thousands of people worldwide. After the introduction of the replacement insole style in 2008, we renamed our original insoles the UltraThin. If you need to dress up and wear fancy shoes that don't have removable insoles, choose the UtraThin style. You can also place them under or on top of removable insoles in any shoe or boot.

Great for these kinds of shoes.

Light Weight and Thin

The advantage with the UltraThin insoles is that they are basically flat and very thin, about 3/32 inch in the main body except the technology underneath the first metatarsal and big toe which adds another 9/64 inch (3.5 mm) at the medial edge. The 6.0 mm insoles add 15/64 inch on the medial edge of the forefoot.

With or Without Arches

The ProKinetics UltraThin Insoles are available with two levels of optional arch supports. Before you add arches to your purchase, we suggest you read our position on using arches. We only recommend them if you have flexible flat feet or for temporary use while curing Plantar Fasciitis. If you mildly over pronate go with the #1 arch (approx. 1/4 in high at the apex). If your over pronation is severe, the #2 arch will be helpful in mid stance (slightly over 3/8 in at the apex). These arch supports are firm but not like hard orthotics.

When you order, choose your insole size first, then in the box below, choose no arch or the #1 or #2 arch support.

If you are here because you were looking for traditional arch support insoles like Superfeet, Protalus, Dr Scholls, Spenco and others, you have inadvertently come to the "right place" because insole technology has changed. Instead of supporting your feet, the ProKinetics® UltraThin Insoles above use small comfortable dimensions that stimulate your central nervous system to make your muscles work correctly to support your feet. The Ultrathin insoles may be fitted with arch supports, but unless you have flexible flat, and we mean totally flat feet or a raging case of Plantar Fasciitis, you won't need them. So, if you searched for Arch Supports and you found us, consider this your lucky day!
