Are you an A Quad?


The A QUAD Foot-Type is commonly thought of as an over-supinated or severe Pes Cavus foot. This condition, also known as a Torque Foot, occurs when a Uncompensated Rearfoot Varus is coupled with a Large Rigid Forefoot Valgus.

We fondly refer to the A QUAD Foot-Type as our “chandelier shakers”! Why? Because this foot-type loads heavily on the ground and never seems to pronate, leading to poor shock attenuation.

The development of heel and lower back pain is common. The torque foot nature of this foot-type allows the valgus forefoot to offset the uncompensated inverted heel alignment that would normally lead to a toe out gait pattern (see C Quad foot-type). Overall, the foot progression angle for this person is such that the feet point relatively straight ahead during gait (no toe out) with a narrow base of support, much like a tight rope walker.

All QUADRASTEP Orthotics are available in Regular and Narrow Widths, and with a topcover an an additional charge. For more information see nolaro24.com

Are you a B Quad?


The B QUAD Foot-Type is a mildly over-pronated foot type or Mild Pes Planus. This is the result of a Compensated Rearfoot Varus with a flexible forefoot valgus deformity. It is often to be found unilateral and is often associated with a structural leg length discrepancy.

The B QUAD Foot-Type is a rarely occurring combined foot deformity, affecting less than 10% of the population. In addition, it is often unilateral. The B QUAD Foot-Type is a mildly over-pronated foot due to a compensated rearfoot varus deformity, however that over pronation is somewhat minimized by a forefoot valgus deformity that acts like a “pronation-deterrent”.

In some cases, this foot-type may be caused by an acquired plantarflexed 1st ray, functioning as a forefoot valgus. This may occur in flexible pes planus foot types as the peroneals are working overtime to try and pull the forefoot into a pronatory twist in attempt to stabilize the midtarsal joint. It is also common to see this condition occur unilaterally on a short limb. Pronating the forefoot into a valgus alignment supinates the foot and helps lengthen the limb. When this foot-type occurs on one side only, we refer to this as a “foot disparity”. When foot disparities occur, each foot functions differently from one another, as so each limb functions differently as well. This has a direct affect on the hips and low back, often leading to sacral-iliac pain. Heel and lower back pain is common. The torque foot nature of this foot-type allows the valgus forefoot to offset the uncompensated inverted heel alignment that would normally lead to a toe out gait pattern (see C Quad Foot-Type). Overall, the foot progression angle for this person is such that the feet point relatively straight ahead during gait (no toe out) with a narrow base of support, much like a tight rope walker.

COMING THIS FALL! NEW E+ from The QUADRASTEP SYSTEM®

Nolaro24, LLC Introduces the QUADRASTEP® E+ orthotic to its popular QUADRASTEP SYSTEM® LineNEW E+ Orthotic from the QUADRASTEP SYSTEM® by NOLARO24, LLC

Nolaro24™, LLC, founded by Roberta Nole, CEO and Louis J. DeCaro, DPM, proudly introduce our 7th QUADRASTEP SYSTEM® orthotic, the E+, to our revolutionary QUADRASTEP SYSTEM® custom-to-foot-type prefabricated foot orthotics line. The QUADRASTEP SYSTEM® is a state of the art alternative to tradi­tional custom orthotic manage­ment. A smash hit with physicians for over 10 years.

Many practitioners around the world already dispense the six original QUADRASTEP® orthotics effectively with great accuracy on about 80% of all patients. With the addition of our 7th orthotic (the E+), we believe practitioners will be able to effectively treat about 90% of all patients.

The QUADRASTEP® E+ orthotic offers more arch support, more forefoot equinus correction, and increased rearfoot posting over the existing E orthotic. The E+ orthotic will not replace the E orthotic, but will allow practitioners to treat virtually every variety of the highly common E QUAD foot-Type. The new E+ offers these alternative design features to more effectively treat the higher arched E’s!

The E QUAD foot-Type is one of the most common and unique looking feet, often with a reverse-lasted foot shape. This foot-type is the result of a combined Uncompensated Rearfoot Varus, coupled with a moderate to large Forefoot Varus. The E QUAD foot-type is one of the most destructive foot-types of all. The combined uncompensated rearfoot and forefoot varus deformities in this foot-type create a very rigid foot that is unable to provide the motions necessary to load the medial aspect of the foot during the stance phase of gait. The key note feature of this foot-type is by far the ballistic heel whip that is evident at heel rise. The larger the forefoot varus deformity the bigger the heel whip, the larger the toe sign, and the greater the chance of kicking themselves in the opposite leg. Our QUADRASTEP® E does a great job at controlling this foot but mostly for the lower arch variants. The QUADRASTEP® E+ will have all of the benefits of the QUADRASTEP® E, but with a more aggressive arch to control those feet with a higher arch.

In today’s practice, the “ideal” method of treating patients via custom orthoses is often time and cost prohibitive due to declining reimbursements. In contrast, off-the-shelf “arch supports”, al­though less expensive, usually lack adequate biomechanical support. The QUADRASTEP SYSTEM® bridges the gap between custom and non-custom orthoses.

Unlike other off-the-shelf orthotic systems that offer only a “one-shape-fits-all” arch support, the QUADRASTEP SYSTEM® offers 7 Quad specific functional orthoses in two widths, each biomechanically tailored to that of a true custom prescription.
