Patent CN212728807U
Updated October 25, 2026Left-Right Specific Soccer Socks: Grip for the Plant Foot, Touch Pads for the Kicking Foot
Grip socks have become standard kit for soccer players who are tired of their foot sliding inside the boot. Most are still made as two identical socks. This design treats the two feet differently, the way a right-footed player uses them. The left sock is for the plant foot, which has to stay put while the other leg swings: it carries silicone grip dots on the toe, heel and the sole between them, a brushed lining for cushioning and a non-slip elastic band across the instep. The right sock is for the kicking foot: bubble-shaped knitted pads on the inner and outer sides soften the ball's impact and help control, and grip strips keep the foot from sliding. Both socks have knitted cushion bumps over the shin and ankle and mesh panels at the back of the calf and on the instep.

The problem
Soccer players lose power and balance when the foot slides inside the boot, and standard team socks give no cushioning where the ball and opponents’ studs hit. Grip socks help, but they are usually two identical socks. According to the patent, the two feet do different jobs in soccer: for most players the left foot is the supporting foot that needs grip and stability, and the right foot is the dominant foot that needs protection and better ball control.
The solution
The patent knits the two socks for their jobs:
- Both the left sock (1) and right sock (2) have protective bumps (3) knitted into the front of the leg (11 / 21) and around the ankle.
- The back of each leg and the instep (14 / 24) have a mesh ventilation structure (4). The legs are wider at the top and narrower at the bottom.
- Left sock (plant foot): silicone grip patches (5) on the inside and outside of the toe (13), on the heel (12) and on the foot between them; a brushed (napped) lining inside the toe, heel and sole; and a non-slip elastic band (6) running up to the mesh on the instep.
- Right sock (kicking foot): bubble-shaped protective bumps (3) and grip strips (7) on the inner and outer sides between toe (23) and heel (22); a brushed lining behind the strips and in the toe and heel; and the same non-slip band (6).

Who it is for
- Soccer apparel brands adding a performance grip sock with a clear story: one sock for the plant foot, one for the kicking foot.
- Team kit suppliers outfitting clubs, academies and high school teams in custom colors.
- Sporting goods retailers with private-label soccer lines looking beyond generic grip socks.
- Online sock brands selling performance socks for soccer, futsal and indoor play.
How it works
The main parts
| No. | Part | What it does |
|---|---|---|
| 1 | Left sock | For the supporting foot - grip and stability. |
| 2 | Right sock | For the kicking foot - pads and control. |
| 11, 21 | Sock legs | Wider at top; knitted bumps at the front. |
| 3 | Protective bumps | Knitted cushions on shin, ankle and (right sock) foot sides. |
| 4 | Mesh vents | Back of the leg and instep. |
| 5 | Silicone grip patches | Left sock toe, heel and sole. |
| 6 | Non-slip elastic band | Holds the sock to the foot at the instep. |
| 7 | Grip strips | Right sock inner and outer sides. |
Wearing them
- Pick the sides - the plant-foot sock goes on the supporting foot, the padded sock on the kicking foot (left-footed players swap them).
- Pull up the legs over shin guards; the tapered shape keeps the guard in place.
- Lace the boots - grip patches and strips hold the foot against the insole and boot sides.
- Wash inside out to protect the silicone prints.
Applications
Club and academy teams
Kit suppliers can offer a team grip sock in club colors with a left-right story players notice.
Cut-leg sock wearers
Many players cut their team socks and wear grip socks underneath; this design can be made as a short grip sock with the same left-right zones.
Futsal and indoor soccer
Players on hard courts need grip inside flat-soled shoes, where the plant foot slides most.
Youth soccer
Cushioning over the shin and ankle adds comfort for young players who take knocks.
Recreational adult leagues
Weekend players buying their own gear look for socks that help with blisters and slipping.
Where it is less suitable
- Strictly regulated team kit - some leagues require socks in exact team colors and designs; the visible zones must match the kit rules.
- Left-footed players with fixed packs - packs marked left and right need a swap note or a separate left-footed version.
- Lowest-cost team orders - silicone printing and differential knitting cost more than plain tube socks.
Frequently asked questions
Why are the two socks different?
The patent treats the supporting foot and the kicking foot as having different jobs. The plant-foot sock focuses on grip and stability; the kicking-foot sock adds knitted pads for impact and ball control, plus grip strips on its sides.
What about left-footed players?
The patent describes the left foot as the usual supporting foot. Left-footed players simply wear the socks the other way round, or a pack can be offered with the zones mirrored.
How long does the silicone grip last?
It depends on the silicone, print method and yarn. Wash and abrasion tests on samples set the expected life; washing inside out helps.
Can they be made as short grip socks?
Yes. The left-right zones on the foot work the same in a crew or ankle sock worn under a cut team sock.
Do the shin bumps replace shin guards?
No. The knitted bumps are cushioning. Shin guards are still required in organized play and are worn over or under the sock as usual.
Can you match our team colors?
Yes. Sock legs can be knitted in club colors with stripes or logos, while the grip and pad zones stay on the foot.
Can this design be made and sold in the US?
The patent was filed only in China, so it does not restrict the design in the US. It is in force in China until April 2030 at most, and making or selling it there needs the owner’s permission. Grip socks may be covered by other US patents - see Patent & Production - so we recommend a freedom-to-operate check before volume production.

No. IP2M is an independent design and manufacturing service working from the public patent document.
