Plantar Fasciitis & Heel Pain

The pain has a root cause. We treat that.

Plantar fasciitis isn't just inflammation — it's a mechanical problem. FasciaFloat™ is designed specifically for the biomechanics driving your pain.

Your heel hurts because your foot mechanics are pulling on it.

The plantar fascia is a band of tissue running from your heel to your toes. When your foot rolls inward — a common and often unnoticed pattern — it puts the fascia under constant tension. Every step stretches it further.

Over time, that repeated overload inflames the tissue right where it attaches to the heel bone. Padding helps with immediate comfort. It doesn't stop the rolling. Generic arch supports lift the arch — but don't address the rotational mechanics driving the problem. FasciaFloat™ does both.

Where it hurts most

Pain at the base of the heel — often worst with the first steps in the morning, or after long periods of rest.

Four things happening in your foot right now.

01

Foot rolls inward with every step

Subtalar pronation — your foot rolling inward — is the underlying driver. It twists the fascia with each footfall. The rolling is the root cause. Most treatments ignore it.

02

Fascia stretches beyond its tolerance

The tension accumulates at the calcaneal insertion — where the fascia meets the heel bone. Not just once — thousands of times per day. Eventually the tissue becomes inflamed.

03

Heel fat-pad can't absorb the impact

Under bodyweight, the fatty cushion of the heel expands outward. A shallow heel cup lets it escape. Deep containment is critical for absorbing load and protecting the underlying tissue.

04

Achilles tension adds to the load

The plantar fascia and Achilles tendon are biomechanically linked. A small heel lift reduces fascia resting length — decreasing baseline tension before you even take a step.

How FasciaFloat™ addresses each one.

Every design element maps to a documented biomechanical rationale. Nothing is generic.

Foot rolling inward — the root cause of the tension
FixedRearfoot post corrects the roll, not just the symptom[R]
Fascia stretched too far with every step
Fixed3 mm heel lift reduces that stretch at the source[8]
Direct pressure on the insertion point and spur site

Built on 65 years of Root biomechanics. Applied to this condition.

In 1959, Dr. Merton Root established the functional orthotic framework that trained podiatrists and orthotists have practiced from ever since. Subtalar joint neutrality, midtarsal mechanics, rearfoot posting — documented, peer-reviewed, replicable.

KevinRoot Medical trained within that tradition. FasciaFloat™ applies the same principles — bespoke, per order, reviewed before fabrication begins.

Every structural decision in FasciaFloat™ traces back to a specific pathomechanical rationale. Nothing is borrowed from a generic orthotic template. The heel cup depth, the posting angle, the groove position — each was chosen because the literature says it works for this condition.

The clinical rationale section below documents those decisions in full, with citations, for providers and patients who want to understand exactly what they're getting.

Rearfoot posting Extrinsic varus/valgus corrects subtalar pronation — the rotational driver of fascia tension. Distinct mechanism from arch support; additive to it. Root, 1959
3 mm heel lift Bilateral lift reduces plantar fascia resting length, decreasing tensional load at insertion regardless of unilateral presentation. Cheung, 2006
Plantar fascia groove Horseshoe pad offloads calcaneal insertion and spur site. Heel cushion substituted when spurs absent. Rosenbloom, 2011
16 mm heel cup Deep cup controls calcaneus eversion/inversion and contains fat-pad expansion under full bodyweight load. Rosenbloom, 2011
Polypropylene shell Weight-adjusted for 5–10% give and rebound. Semirigid control with cushion extension to toes. Olson, 1996
