Massage Insole with Spring-Back Silicone Nubs and a Removable Top Layer

The problem

Massage insoles with molded bumps are a popular add-on for people who stand or walk all day, but most are a single sheet: the bumps are rigid, they press the same spots for hours, and when the surface wears or gets dirty the whole insole is replaced. The patent describes conventional massage insoles as pressing on the sole continuously, which can become uncomfortable over long wear.

The solution

The patent separates the insole into layers that each do one job:

1. An insole body (1) has a lower layer (11) whose edge rises into a raised rim (2), forming a shallow tray.
2. A step (3) runs around the top of the rim on its inner side, with reinforcing ribs (4) underneath; the upper layer (12) rests on this step and can be lifted out by a pull tab (10).
3. The upper layer has through-holes (5) at points the patent maps to acupoints of the sole.
4. Between the layers lies a soft massage cushion (6) with hemispherical silicone nubs (7), one under each hole. The nubs are taller than the upper layer is thick, so they stand slightly above it.
5. An elastic layer (9) sits between the cushion and the lower layer.
6. The cushion is made of three detachable pieces - forefoot (61), midfoot (62) and heel (63) - joined by matching projections and recesses (81/82, 84/85).

According to the patent, when the wearer steps down, the nubs press the sole; at the same time they compress the elastic layer and move back through the holes, which reduces how long they stay in hard contact. When the foot lifts, the elastic layer pushes them up again, while the upper layer supports the foot.

Who it is for

• Insole and foot-comfort brands wanting a massage insole whose parts can be replaced instead of the whole product.
• Workwear and safety-footwear suppliers selling comfort insoles to people on their feet all shift - retail, warehouse, healthcare and hospitality staff.
• Wellness and reflexology retailers who already sell foot rollers and massage mats and want a wearable product in the same line.
• Shoe brands looking for a removable massage footbed for walking or casual shoes.

How it works

The main parts

Using it

1. Trim and insert the insole like an ordinary footbed.
2. Walk normally. Each step presses the nubs against the sole and pushes them down into the elastic layer.
3. On lifting the foot, the elastic layer returns the nubs to their raised position.
4. To clean, pull the top sheet out by its tab; the cushion sections can be lifted out and replaced one at a time.

Applications

All-day standing jobs

Cashiers, nurses, warehouse pickers and line workers often buy comfort insoles themselves. A nub insole that yields under load suits long shifts better than rigid bumps.

Walking and travel shoes

Tourists and walkers who already like massage sandals can have a similar feel inside closed shoes, with a top sheet that can be washed after a trip.

Reflexology and wellness retail

Shops selling foot-reflexology charts, rollers and mats can add a wearable item; the hole map can follow the shop’s own reflexology chart.

Replacement-part business model

Because the top sheet and cushion sections are separate, a brand can sell refill top sheets or nub cushions of different firmness.

Gift and promotional sets

Massage insoles are a common gift item; the layered design gives room for colored nubs and printed top sheets.

Where it is less suitable

• Running and high-impact sports - loose layers and nubs are not designed for sprinting or jumping; a performance insole is a different product.
• People with diabetic or sensitive feet - textured insoles can cause pressure points; such users should follow their clinician’s advice, and the product should not be marketed to them.
