The Idea
Height boost insoles that stay your secret
These height boost insoles slide into the shoes you already own and quietly add up to 3.5 cm of lift — no visible platform, no chunky sole, nothing to explain. A little extra height can change how a room, a date, or a job interview feels, and these insoles get you there without swapping a single pair of shoes. Just drop them in, lace up as usual, and stand a little taller.
Because the lift lives inside the shoe instead of underneath it, it works with sneakers, boots, dress shoes, and work shoes alike — anywhere there's a little extra room at the heel. Three height options mean you can go subtle for the office or step it up for a night out, and switch between shoes without switching insoles.
Built To Wear All Day
Breathable, cushioned, and shaped to move with you
The top layer is a perforated, sweat-wicking mesh that keeps air moving through the shoe, so the lift doesn't come at the cost of comfort. The raised heel wedge is shaped with an ergonomic curve that sits naturally under your heel and arch instead of forcing your foot into an odd angle.
Made To Fit Your Shoe
Trim it down, wear it anywhere
Each insole can be trimmed at the front edge to match the exact shape of your shoe, so it never bunches, slides, or peeks out the toe box. When they need a refresh, both layers are reusable and washable — no replacing a pair every few weeks.

FAQ
Common questions
Can other people tell I'm wearing them?
No. They sit fully inside your shoe under your foot, so there's no visible platform or heel — just a bit more height.
Which height should I pick?
1.5 cm fits almost any shoe, low or high. 2.5 cm suits regular sneakers and athletic shoes. 3.5 cm works best in taller shoes like high-tops or boots that have more room inside.
Do I need to trim them?
Only if your shoe runs narrow or short at the toe. Each insole can be trimmed along the front edge to match your shoe's shape.
How do I clean them?
Wipe with a damp cloth or rinse by hand and air dry. They're reusable, so a quick clean keeps them fresh for reuse.
What comes in the box?
One pair of insoles at the height and size you select at checkout. Fit both shoes with the same height for a natural, even feel, or mix heights across different pairs of shoes in your closet.

I put the Ergokliniken insoles in my work shoes and noticed the difference straight away. My feet feel much less tired at the end of the day.
The balance board looked simple, but after a few minutes I could really feel it through my calves and ankles. It’s become part of my morning routine.
What I like most is that they’re simple products you can actually use in everyday life. Nothing complicated, just small things that make my routine more comfortable.
