Hard floors · Long shifts · Steady footing
Insoles for standing all day — the floor stops taking it out of you
Concrete, tile and sealed vinyl return none of the energy you put into them, and a shift spent standing still loads your feet harder than one spent walking. Springbak® Springsoles are 3/32 of an inch of the most resilient material in the world, and they go under the insole already in your work shoes. In force plate testing at Weber State University, it took more than twice the force to push a person off the plate while standing on Springsoles as it did without them.
Who spends the day standing
The floor does not care what the job is. If your shift happens on a hard surface, the arithmetic underfoot is the same.
Nurses & hospital staff
Twelve-hour shifts on sealed concrete and vinyl tile, most of it standing, with no chance to sit when your legs start talking.
Teachers
Six hours on your feet in front of a class, then hall duty, all of it on the hardest floor in the building.
Retail, hospitality & food service
Standing behind a counter or a line, pivoting on the same spot on a mat-over-concrete floor for a whole shift.
Warehouse, manufacturing & trades
Steel-toe boots on concrete, carrying and lifting, where footing has to be sure and legs are done before the day is.
Barbers, stylists & dental staff
Standing nearly still for hours, leaning and reaching, which loads your feet harder than walking does.
Anyone at home on hard floors
Tile and hardwood give nothing back either. Household hours add up the same way a shift does.
Why a resilient layer beats a thicker one
Hard floors return none of your energy
Concrete, tile and sealed vinyl absorb the energy of every footfall and give none of it back. Over a shift your feet, legs and lower back pay for every one of those steps. Springsoles are made from 1,4-polybutadiene — one of the most resilient materials in the world — so instead of swallowing each step, the layer under your foot returns a share of that energy into the next one.
Standing still is the hardest part
Walking shares load between legs and moves it around. Standing in one place does not. That is why a stationary shift can hurt more than a walking one, and why a stable, resilient base underfoot matters most to people who stand rather than move.
Grounded stance: over twice the force to displace you
In force plate testing at Weber State University's human performance lab, it took more than twice the force to push a person off the plate while standing on Springsoles as it did standing in the same shoes without them. That is the anchoring effect — a measured stability difference, standing still. On a wet kitchen floor, a loading dock or a hospital corridor, steadier footing is worth as much as comfort.
3/32 of an inch — your work shoes still fit
Springsoles slide under the insole already in your shoes or boots. Nothing about your fit, your lacing, your safety toe or your prescribed orthotic has to change, so nothing about your footwear has to be re-broken-in.
The force plate study
The grounded-stance finding, in plain terms
Springsoles were tested on a force plate at Weber State University's human performance lab. Standing on Springsoles, it took more than twice the force to displace the subject off the plate than it did standing in the same shoes without them. The finding held for athletes and for people simply standing — which is the situation a nurse, a machinist or a stylist is in for most of a shift.
“Our department sponsored a strength and stability study at the Weber State University human performance lab. After reviewing the force plate data, showing it took more than twice the force to push off the subjects off the force plate when standing on Springsoles, we have to conclude there is significant strength increase to individuals utilizing Springsoles.”
That stability comes from the material, not from bulk — and it is covered by four U.S. patents, the first ever issued for performance-enhancing shoe components. See the four U.S. patents and the Weber State force plate study or the full lab record.
Fitting them in work shoes and boots
- 1.Lift the existing insole out of your work shoes, sneakers, clogs or boots.
- 2.Lay the Springsole in flat, then set your original insole back on top of it.
- 3.Trim the toe along your outline with scissors if the shoe is snug.
- 4.Wearing a prescribed orthotic? The Springsole goes underneath it — the orthotic still does its job.
- 5.Put a pair in every pair you actually work in, so your footing feels identical shift to shift.

Questions from people on their feet all day
What are the best insoles for standing all day on concrete?
Look for two things: a material that returns energy instead of only absorbing it, and a profile thin enough that your work shoe still fits correctly. Springbak® Springsoles are 3/32 of an inch of 1,4-polybutadiene, one of the most resilient materials in the world, and they sit under the insole already in your shoe. Thick foam feels soft in the store and flattens out under a shift; resilience is what still works at hour ten.
Do these help with foot and leg fatigue at the end of a shift?
That is the most common thing people on their feet all day report to us. Hard floors return none of the energy you put into them, so every step costs you the full amount. A resilient layer under your foot returns part of each step, which is what reduces the beat-up feeling by the end of a long day. Springsoles are not a medical device and do not treat any condition.
Are these good insoles for nurses working 12-hour shifts?
Yes — nurses, hospital techs and dental staff are among the people who buy them most, because a hospital floor is about the hardest surface anyone works on and the shifts are the longest. They fit in clogs, sneakers and slip-resistant work shoes with removable insoles.
Will they fit in steel-toe work boots?
At 3/32 of an inch they fit under the insole of nearly any boot with a removable insole, including safety-toe boots. Because they go beneath your existing insole, they do not raise your foot into the toe cap the way a thick replacement insole can.
Do they help with balance and stability on slick or uneven floors?
Force plate testing at Weber State University found it took more than twice the force to displace a person standing on Springsoles compared with standing without them. That anchoring effect is the same finding we cite for linemen and for seniors, and it applies to anyone standing on a wet, waxed or uneven floor.
Can I use them with my orthotics or arch supports?
Yes. Place the Springsole underneath your orthotic or arch support. The orthotic keeps providing the support it was prescribed for, and the Springsole adds the resilient layer beneath it.
How long do they last and what do they cost?
Each pair is $29.95 and made in the USA. 1,4-polybutadiene is chosen for resilience rather than cushioning, so it does not pack down and go flat the way foam does under daily wear.
What size should I order?
Order your US men's or US women's size range and trim the toe to fit. If you are between ranges, order the larger one and trim along the outline of your original insole.
