How to use ?
① Set your angle
Slot the support peg into one of the 5 incline positions. If you're new or in significant pain, start at the lowest angle (25°). You'll work up from there over the coming weeks.
Beginners: start at 25°
② Stand on the board
Place both feet fully on the surface, toes elevated, heels lower. Stand upright — hands free. Hold for 1–3 minutes, or perform 3 sets of 15 slow eccentric heel drops. Do this 2–3 times daily.
While your coffee brews works perfectly
③ Progress over weeks
As stiffness decreases and flexibility builds, move to the next incline level. The 12-week protocol in your Exercise Blueprint guides you step by step — no guesswork.
Total daily commitment: 5–10 minutes.The most consistent users aren't the ones who carve out workout time — they're the ones who keep the board visible and step on it whenever they walk past it.

5 Minutes a Day.A Body That Finally Works.
When you address the calf tightness driving everything downstream, the benefits don't stop at your heel. They travel up the entire chain — exactly where your pain has been living.

Pain-free mornings
Pain-free mornings
The stabbing first-step pain is caused by the plantar fascia violently stretching after it has shortened overnight. As the calf-Achilles complex lengthens through the eccentric protocol, that overnight shortening decreases — and so does the pain that greets you every morning.
"Morning stiffness starts to ease within the first 1–2 weeks for most users."
Knee & lower back relief
Knee & lower back relief
32% of foot pain sufferers also report knee, hip, or lower back pain — because the same restricted dorsiflexion forces the knee and lumbar spine to compensate with every step. When the calf unlocks, the compensation stops. The chain heals from the ground up.
KURU Foot Pain Trends Report, 2025 — 32% of foot pain sufferers report concurrent knee/back pain.
Restored mobility & flexibility
Restored mobility & flexibility
Ankle dorsiflexion — the range of motion your body needs to walk, climb stairs, squat, and stand up from a chair — measurably improves with structured incline board use. Hafeez et al. (2024) documented clinically significant gains after just 4 weeks of daily use.
Hafeez et al., Journal of Health, Rehabilitation & Research, 2024.
Faster recovery from activity
Faster recovery from activity
Eccentric loading doesn't just stretch the tissue — it strengthens tendons and repairs the micro-damage that accumulates from running, hiking, or standing. Users report bouncing back from workouts and long days on their feet significantly faster once the protocol is established.
"Makes a huge difference before golf — started using it after my runs and it's a game changer." — Verified customer, Geoffrey F.
Balance & fall prevention
Balance & fall prevention
Restricted ankle mobility is a leading contributor to balance issues and fall risk in older adults. The StretchRX's incline position restores dorsiflexion range and activates the tibialis anterior — shifting the body's center of gravity forward and improving proprioception with every
use.Clinical study: 30-day incline board program significantly improved walking velocity and Timed Up and Go performance. PMC / J. Physical Therapy Science, 2016.
Surgery prevention
Surgery prevention
The AAOS lists calf stretching as a first-line treatment for plantar fasciitis — before injections, before orthotics, before surgery. Every week of consistent eccentric loading is a week of building the tissue strength that makes invasive intervention unnecessary. Strong tendons are the most cost-effective insurance policy you own.
"I bought this to avoid surgery. That was 4 months ago. I haven't looked back." — Verified customer
Your Heel Isn't the Problem.Your Calves Are — And Here's Why.
Here is what has been happening in your body for years — probably decades — without anyone explaining it to you.

Shortened calves restrict ankle dorsiflexion
Shortened calves restrict ankle dorsiflexion
Dorsiflexion is your ankle's ability to bend toes-toward-shin. Every step, every stair, every squat requires it. When your calves are chronically tight, this movement is restricted. And your body doesn't stop moving — it compensates.
Your knees, hips, and back absorb the compensation

The Achilles tendon and plantar fascia are continuous
Published in the Wiley Medical Journal (2021): the Achilles tendon continues around the heel bone and becomes the plantar fascia. When the Achilles is chronically tight, it tensions the plantar fascia — all night long as the tissue shortens during sleep, then violently stretches with your first step in the morning. That 'broken glass' sensation you feel? It was never just your heel. It was always your calf.
Customers feel the difference
-
The slot system is genius — this thing actually adjusts
I was skeptical it would feel different from leaning on a step. The moment I stood on the lowest angle I understood immediately. The stretch reaches somewhere nothing else has. I'm on the third level now. Four weeks and my knee pain has almost disappeared too.
-
I didn't think a board could do this
I genuinely laughed when my daughter suggested this. I've had heel pain for three years and tried everything. Two weeks in I stopped limping to the kitchen in the morning. I'm honestly shocked. My only regret is not trying it sooner.
-
Back running. No more Achilles drama.
Eight weeks of PT, two cortisone shots, four months of barely running. I found this, used it after every run, and within five weeks the tightness that had been stopping me was gone. It just sits by the door. I use it every single day.
You Must to Know Before You Order
How long before I notice a difference?
How long before I notice a difference?
Most customers notice less morning stiffness within the first two weeks. Clinical research on structured incline board stretching (Hafeez et al., 2024) found clinically significant ankle dorsiflexion improvements after four weeks of daily use. By week four to six, most users report that everyday movements — stairs, standing, walking — feel noticeably easier. The 90-day guarantee gives you a full three months to be certain.
I've tried stretching before . Why is this different?
I've tried stretching before . Why is this different?
Because not all stretching is the same mechanism. Wall stretches and foam rollers produce passive lengthening — temporary and non-structural. The StretchRX enables eccentric loading on an inclined surface, which is what the Alfredson protocol — the 30-year clinical gold standard for Achilles and plantar fascia treatment — requires. It is a fundamentally different intervention, which is why it produces fundamentally different results.
How much time does it actually take?
How much time does it actually take?
Two to ten minutes is all you need. Stand on it while your coffee brews. Put it under your desk and step on it between calls. Use it while watching TV. The most consistent users are not the ones who carve out workout time — they are the ones who let the board become a natural part of existing moments in their day.
Is it safe for beginners and seniors?
Is it safe for beginners and seniors?
Absolutely. The adjustable angles allow you to start at the gentlest incline and progress only when comfortable. The wide, non-slip platform eliminates the instability that makes stairs and steps risky. The StretchRX is used by people in their 70s and 80s who want to maintain independence and mobility — not just competitive athletes.
Should my knees go over my toes?
Should my knees go over my toes?
Yes — and modern physical therapy is unambiguous about this. The old "never let your knees go over your toes" advice originated from a single 1978 study at Duke University and has since been comprehensively revised. Your knees go past your toes every time you walk downhill, climb stairs, or stand up from a chair. The key is controlled, progressive loading — which is exactly what the StretchRX is designed to deliver.
What if it doesn't work for me?
What if it doesn't work for me?
Return it. The 90-day money-back guarantee means you have three full months to use the board daily and evaluate the results. If you don't feel a meaningful difference, contact us and we will issue a full refund — no questions, no conditions, no hassle. We can offer this because the clinical evidence is strong and the vast majority of users notice real change well before the 90 days are up.
