On Sale Now! $41.95 per pair

L400 Lynco Biomechanical Orthotics look like cushion insoles but are actually arch supports that stabilize the foot and effectively control over-pronation. Do you need metatarsal support for the ball of your foot? Check out the L405 Lynco Insoles for arch support and metatarsal support.
Lynco orthotic arch supports - top and bottom

Lynco L400 arch supports Insoles are suitable for almost any arch height from low to high. However, people with naturally low arches may need to take a few days to get used to the feel of the arch supports and become fully comfortable with them. Most people with medium to high arches will find the Lynco arch supports immediately comfortable and supportive.

Lynco arch supports are ideal for people that need considerable support but have tried hard plastic arch supports and found them to be too uncomfortable to wear. Their triple layer design (discussed below) creates an extremely supportive foot bed that is amazingly comfortable and easy to get used to.

Triple Layer Design For Support and Comfort

The design of the Lynco orthotic arch supports incorporates a semi rigid rubber core for stability and support, surrounded by two distinctive layers of cushioning foam for unparalleled comfort
These arch supports are designed for people with Medium & High Arches

The Bottom Layer
The blue bottom layer of foam on the L400 Lynco arch support is called Plastazote® foam and it is a closed cell, cross-linked polyethylene foam. Plastazote® foam is made by a unique high pressure nitrogen gas solution process that results in a superior polyethylene foam than other polyethylene foam making technologies. This process creates an inert foam, free from chemical residues and with a more uniform and regular cell structure than other foams. The

uniform and regular cell structure means that the foam is particularly strong and durable. Apex uses this foam on the Lynco L400 arch supports because it not only provides superior comfort and cushioning but once the foam is molded (during manufacturing) into the curved, arch support shape (pictured above) the foam actually has enough internal strength to add additional support to the arch support thereby improving its over all function.

The Middle Layer (Not Visible In Picture)
The middle layer (not visible) is a contoured Pedic™ rubber core. The rubber core is the main feature that gives Lynco arch supports their long lasting and high level of support. The rubber core runs from the Lynco orthotic arch supports side view
heel to the ball of the foot and is contoured to support the medial and lateral arch. The rubber itself is firm but retains a certain level of flexibility that plastics cannot. This makes L 400 Lynco arch supports more immediately comfortable then most hard plastic arch supports and orthotics. Once the rubber core is joined to the contoured bottom layer of Plastazote® the two pieces enhance each other’s strength and dramatically increase the overall support and comfort of the arch supports.

The Top Layer
The very top layer on the L400 Lynco arch support is a red polyester cover but right under that is the main top cushion layer. It can be seen as a strip of black in between the red and the blue layer. This top cushion layer is a 1/8-inch thick layer of an open cell polyurethane foam that is particularly soft and bouncy. Its purpose is to add additional shock absorbing ability and to make the arch supports softer and more comfortable. The top red polyester cloth layer is very smooth and provides a cool, friction free surface against the foot. Lynco orthotic arch supports top view
