The Foundation by Solbase
The insole for burning, numb feet that finally holds up under you. Engineered for 200–350 lbs, it spreads your weight across the whole foot, every day, in the shoes you already own.
Spreads your weight – Across the whole sole, not three sore points
Built for your weight – Engineered for 200–350 lbs, not a 150-lb average
Firm, not hard – A rigid TPU shell under 45–60 kg/m³ high-density foam
Fits your shoes – Trim to fit: sneakers, casual shoes, boots
🛡120-day money-back guarantee. If they flatten or your feet still hurt, you pay nothing.
Description
Your feet can't warn you when the support under them is gone.
Every insole on the market is built around one assumed body: 130–170 lbs. Put more weight on it every day and the foam gives up early. With neuropathy, that matters more. A foot that can't fully feel the floor gets no warning when the foam under it has given out. It keeps landing on the same three points, the heel, the ball of the foot and the big toe, thousands of times a day, and the evenings get worse.
The Foundation is built the other way around, starting from the weight it has to carry: a rigid TPU shell that keeps its shape, high-density foam on top, and a deep heel cup, so your weight is spread across the whole sole instead of three sore points.
Load-rated: Engineered for 200–350 lbs
Holds up: Months of daily wear
Risk-free: 120-day money-back guarantee
What to expect
The first dayIt feels firmer than you're used to. That's the shell holding your arch up instead of letting it sink. Most people wear them from the first morning. Keep checking your feet daily, the way your doctor told you to.
The first weekThe hours on your feet are the same. What you notice is the evening, when the burning used to start.
Weeks three to sixThis is when standard foam gives out under a heavier body. Press your thumb into the heel. It springs back.
Months laterMonths of daily wear, and the pair you're standing on still does its job.
120-day guarantee
120-day full refund. If your feet still hurt, or a pair flattens out on you within 120 days, contact us for a complete refund. You have nothing to lose except the pain.

Why the evenings get worse
It isn't only the nerves. It's what they land on all day.
If you have neuropathy and weigh over 200 lbs, you've been told to manage your blood sugar, lose weight and buy cushioned shoes. The nerves are what they are. What you can change is the foam under them, and most of it gave out weeks ago.
Feet that burn by evening and worse once you sit down
Numb toes, checking the ground with your eyes
Insoles that go flat within a few weeks
Creams and gadgets that only work while you use them
Pressure, spread out
Support that spreads your weight across the whole foot
Standard foam hits compression set, the point where it stops springing back. For a 250-lb person that takes 3 to 6 weeks, and from then on your weight lands on three points. Spreading the pressure so no single point carries it is what doctors aim for with a diabetic foot. The Foundation is engineered to keep doing it.

They had tried everything for their feet
Burning, aching feet that gave out by evening. Six people who had tried everything else, filmed on their own phones a week or two after their insoles arrived.

"I've been in manufacturing 25 years — 8 to 12 miles a day on a 12-hour shift. By day two my feet were killing me, and my orthopedist told me to get an insert with real structure. I've tried Dr. Scholl's, Superfeet, a bunch of others — the heel cups always break down. Two weeks in, these are holding up really well. Probably the best I've seen."

"An hour after I started working, my feet, I feel like I was walking on glass. … Now with these new insoles from Solbase, I'm on my feet all night. The feet don't bother me. I can come home and I can even go to the gym now."

"I had plantar fasciitis pretty severely — podiatrists, shots, every insole I could find. Solbase is very sturdy and very comfortable, and I feel like they're really going to last. They've worked well for me, and I believe they'll work well for you too."

"I spent quite a bit of money on over-the-counter arches, custom-made arches, quality shoes — and nothing has really helped. Yours do."
"I have a very high instep, and nothing seems to work properly. Solbase are the best ones I've had, and I would definitely recommend them for anyone who does need insoles."
"I'm 265 lbs and I've tried every insole on the market. They all went flat within a month. I put these in on Monday. It's now Saturday and I've done six shifts on them. My feet don't feel like they've been through a war at the end of the day. I actually cried a little on Thursday because I wasn't in pain at 8pm. That sounds dramatic but you'd understand if you'd been where I was."

"I'm a 330-lb guy. My doctor kept telling me to lose weight. Meanwhile I still had a job and a family and needed to get through the day. These are the only insoles that have actually held up. Months in and they still feel like day one. Nothing I've tried before has lasted three weeks."

"290 lbs, on a warehouse floor ten hours a day. I'd given up — figured this was just my life now. Six weeks in these are still holding when every drugstore pair I owned was flat in two. I don't think about my feet at the end of the day anymore. That's the whole thing right there."

"Been a mechanic 28 years, 275 lbs, concrete all day. My knees had started going and I blamed my age. Put these in and about two weeks later I realized the ache on the drive home was gone. Didn't expect that. Wish I'd had them a decade ago."

"I bought them because of the guarantee, honestly. Figured I'd send them back like everything else. It's been four months. They're still in my boots. That's the longest any insole has lasted me at 300+ pounds, and it's not close."
Robert M., Construction, 305 lbs · ✓ Verified buyer
It won't repair nerves. Nothing we know of can. What it changes is what your feet land on all day: a firm, load-rated foundation that spreads your weight across the whole sole instead of three sore points. That's why people with neuropathy and diabetes order it, and many feel the end of the day get easier within the first week. Keep doing what your doctor told you.
Isn't firm bad for a foot that can't feel?
Firm is not hard. The top layer is high-density foam; the firmness is in the rigid shell underneath that keeps the foam from collapsing. The point is that your weight is spread across the whole sole instead of concentrated on three points. If it doesn't feel right for you, send it back within 120 days.
I can't feel whether an insole fits. How do I check?
Use your eyes and hands, not your feet. Pull out the insole that came with the shoe, lay The Foundation on top of it and trim to the same outline. Check that it sits flat and that the heel cup is at the back of the shoe. A size guide comes with your order. Then check your feet daily, the way your doctor told you to.
Is this a medical device?
No. It is an insole. It is not prescribed and it does not replace therapeutic footwear or inserts your doctor ordered for you.
Which size do I pick?
Pick your shoe size from the five ranges in the offer above. If you're between two, take the larger one and trim it. The size guide next to the sizes shows every range.
Will they fit my shoes?
The Foundation is trim-to-fit and works in work boots, sneakers, casual shoes, and most dress shoes. Remove the existing insole first, then trim if needed.
Do they need breaking in?
They feel firmer than foam on the first day, because the shell underneath doesn't give. Most people wear them from the first morning. If yours feel firm, wear them for a few hours at a time for the first couple of days.
How long do they last?
They're built for months of daily wear at 200–350 lbs. If a pair flattens out on you within 120 days, you get your money back.
When will they arrive?
Free shipping on every order. Ships in 4–7 business days.
What if they don't work for me?
120-day full refund. If your feet still hurt, or a pair flattens out on you within 120 days, contact us for a complete refund. You have nothing to lose except the pain.
