The Alznner arch support is one of the original supports Good Feet® offered its customers. The inventor of this arch support was an orthopedist and physiotherapist who patented the design of the support in 1969, hoping to help improve the lives of all of the people who put it on.

Maintainer Flex


Sturdy enough to take a beating every day in your work boots, the Alznner is still flexible enough to accommodate a wide variety of foot types and activities. The Alznner’s flexibility and features make it ideal for arches of average height and flexibility.

Ideal for:

Stability Structure

The underside of the Alznner features a sturdy pattern of connected squares called a “Stability Structure.” These thick, waffle-pattern shaped squares are positioned under the forefoot of the arch support to help stabilize the support while the foot walks.

What does the stability structure do and how can it help?

The Alznner’s waffle-patterned Stability Structure also helps to prevent unnecessary side-to-side motion of the foot during gait. This stable pattern helps the Alznner retain its arched shape no matter how hard the foot depresses it, ensuring that the many bones of the forefoot are properly supported. This leads to a more stabilized and better aligned foot.

Metatarsal Rise

The “front” end of the Flex Maintainer arch support features a small lump. This is called the “metatarsal rise”. It is designed to help take pressure off the ball of the foot and the toes every time the foot takes a step.

What the metatarsal rise do and how does it help?

By properly supporting the metatarsal arch, the metatarsal rise lifts up the bones in the ball of the foot, effectively preventing them from hitting the ground too hard every time the foot pushes off for a step. This means that the metatarsal rise in the Flex Maintainer arch support can help reduce pain caused by corns, calluses, and excess pressure on the ball of the foot. The Flex Maintainer arch support is also great for helping to create more room for the toes in tight dress shoes, by alleviating pressure from over-stressed toes.

The metatarsal rise on the Flex Maintainer arch support is much less aggressive than the same feature in the Exerciser arch supports. The Flex’s metatarsal rise is designed to provide flexible support to the active foot, preventing the ball of the foot from hitting the ground too hard and distributing pressure away from the toes.

On the Flex Maintainer arch support, the metatarsal rise helps to support the ligaments and tendons in the forefoot as the entire foot works during strenuous or sports activities. The Flex’s metatarsal rise conforms more to the foot, which means it provides just enough support to take pressure off the ball of the foot, without interfering with the foot as it adapts to uneven terrain. The flexibility of the Flex helps it accommodate the needs of the athletic foot for every sport or casual activity.

Heel Cup

The heel cup is a cup-like indentation at the heel end of the Alznner arch support. It is designed to protect the fatty pad of the heel and to help absorb the “step shock” and joint impact that courses through the body each time the heel strikes the ground.

What does the heel cup do and how can it help?

Every step each foot takes begins when the heel makes contact with the ground, in what is called “heel strike.” When the heel strikes the ground, up to three times the body’s weight can be exerted on the bones and tissues of the heel. This puts the heel under tons of stress, especially if it is not properly supported. The Alznner’s heel cup is designed to help cushion and properly align the heel, thereby reducing the stress of each step.

A stable heel is one of the foundations of a stable body. If a heel is striking the ground at an angle, or rolling too much to one side during gait, it can cause imbalances throughout the entire foot, ankle, knees, and eventually through the entire body. By supporting the heel, the Alznner arch support can help align each step starting with the heel strike. While ensuring that each heel strike is balanced and cushioned, the Alznner’s heel cup can reduce fatigue on the ankles, knees, hips, and back. A properly supported heel can properly distribute the weight of the body through the legs during gait, which means that the tendons of the ankles and knees won’t have to work extra hard to keep the body upright.

Inner & Outer Longitudinal Arch Support

The Alznner arch support also features support for the inner and outer arches of the feet. These are designed to stabilize the foot during gait, to help prevent it rolling inward or outward with each step

What does inner and outer longitudinal arch support do and how does it help?

EveryBy supporting all four arches of the foot, the Alznner arch support helps to properly distribute pressure through the entire foot, thereby preventing any one part of the foot from taking on too much pressure. This can help alleviate pain in areas of the foot that are strained.

The Alznner’s inner and outer longitudinal arch support features stabilize the foot during gait, helping to prevent pronation and supination (rolling inward or outward). By stabilizing the foot, the Alznner helps to promote proper gait, thereby reducing excess stress in the ankles, knees and hips.
