ZERO GIVE® RESEARCH • CASE STUDY 01 • 2026
Soccer grip socks are often described as “lightweight,” “thin,” or “low profile.” To compare those claims on the same basis, Zero Give measured seven commercially available performance grip sock samples for pair weight, full-sock toe thickness and full-sock cuff thickness.
Quick result: Zero Give and HAVO Speed X tied for the lowest measured pair weight at 58 g. Zero Give recorded the lowest measured full-sock toe thickness at 3.37 mm and the lowest cuff thickness at 4.40 mm.
Products included
The sample set included Zero Give, HAVO Speed X, Senda Gravity Pro, TRUsox 3.0, APEX, WeFoot and Gain The Edge. Competitor names identify the samples measured. The values below are Zero Give internal sample measurements, not manufacturer specifications.
Testing transparency and public verification
This case study reports testing conducted in-house by Zero Give by Dr. Ralph Carullo. Available recordings are published as primary visual evidence so viewers and independent third parties can inspect the measurement sequence, observe the displayed readings and assess whether the reported weight and thickness measurements are supported by the recordings.
The testing is publicly reviewable and viewer-verifiable, but it is not represented as independent laboratory testing or certification.

| Sample | Pair weight | Approx. per sock | Full-sock toe | Avg. toe-layer equivalent | Full-sock cuff | Avg. cuff-layer equivalent |
|---|---|---|---|---|---|---|
| Zero Give | 58 g | 29 g | 3.37 mm | 1.69 mm | 4.40 mm | 2.20 mm |
| HAVO Speed X | 58 g | 29 g | 3.98 mm | 1.99 mm | 7.06 mm | 3.53 mm |
| Gain The Edge | 68 g | 34 g | 4.32 mm | 2.16 mm | 6.31 mm | 3.16 mm |
| WeFoot | 70 g | 35 g | 4.32 mm | 2.16 mm | 5.82 mm | 2.91 mm |
| TRUsox 3.0 | 76 g | 38 g | 4.47 mm | 2.24 mm | 5.43 mm | 2.72 mm |
| APEX | 76 g | 38 g | 4.58 mm | 2.29 mm | 6.30 mm | 3.15 mm |
| Senda Gravity Pro | 82 g | 41 g | 5.26 mm | 2.63 mm | 6.46 mm | 3.23 mm |
Measurement note: Pair weight was divided by two for the approximate per-sock value. Toe and cuff were measured through the complete flattened sock; the single-layer equivalents are calculated by dividing those raw readings by two. They are not separate direct measurements.
What was the lightest soccer grip sock tested?
Zero Give and HAVO Speed X tied for the lowest measured pair weight at 58 g. Under the same Zero Give full-sock caliper method, Zero Give measured 3.37 mm at the toe and 4.40 mm at the cuff, compared with 3.98 mm and 7.06 mm for the tested HAVO Speed X sample.
HAVO currently advertises Speed-X at 29 g per sock and “as thin as 1 mm in key zones.” Those manufacturer-published figures use a different measurement basis from Zero Give’s complete flattened-sock caliper reading. They therefore should not be treated as directly equivalent thickness measurements. The 29 g advertised per-sock weight does align numerically with 58 g per pair.
How the measurements were handled
The three direct measurements were pair weight in grams, full-sock toe thickness in millimeters and full-sock cuff thickness in millimeters. All seven samples were measured using the same internal method. The normalized per-sock and average-layer values are provided only to clarify the measurement basis.
The dataset does not establish statistical repeatability across multiple production lots, all sizes, wash states or every unit sold by each manufacturer. Product size, production tolerance, sample condition and measurement technique can affect results.
Zero Give vs TRUsox 3.0
The TRUsox 3.0 sample measured 76 g per pair, 4.47 mm at the full-sock toe and 5.43 mm at the cuff. Compared with that sample, Zero Give measured 18 g lighter, 1.10 mm thinner at the toe and 1.03 mm thinner at the cuff.
Those measurements describe construction only. They do not establish traction, durability, comfort or match performance. See the dedicated Zero Give vs TRUsox comparison for the combined construction and pendulum-friction data.
Why weight and thickness should be reported separately
The HAVO result shows why “lightweight” and “thin” are not interchangeable. HAVO Speed X and Zero Give recorded the same 58 g measured pair weight, while their toe and cuff thickness readings differed. A player with a very low-volume cleat may care more about thickness than mass; another player may prefer added cushioning.
Watch the measurements
The original measurement video documents the physical measurement process used for the initial samples. HAVO Speed X and Senda Gravity Pro were added using the same three reported measurement categories.

What this case study supports
- Zero Give and HAVO Speed X tied for the lowest measured pair weight at 58 g.
- Zero Give recorded the lowest measured toe thickness at 3.37 mm.
- Zero Give recorded the lowest measured cuff thickness at 4.40 mm.
- Senda Gravity Pro recorded the highest measured pair weight and toe thickness in this seven-sample set.
- The seven samples differ materially in measured construction.
What this case study does not prove
- That lighter always means better.
- That thinner socks automatically improve speed, agility or skill.
- That every production unit from each brand has identical measurements.
- That the testing is independent laboratory certification.
- That these construction measurements alone establish traction, durability or comfort.
Frequently asked questions
Are the published test videos independent laboratory certification?
No. The testing was conducted in-house by Zero Give by Dr. Ralph Carullo. The recordings are published so viewers and independent third parties can inspect the measurement sequence and displayed readings. This makes the evidence publicly reviewable and viewer-verifiable, but it is not represented as independent laboratory testing or certification.
Is 29 g per sock the same as 58 g per pair?
Yes, mathematically. A 58 g pair corresponds to approximately 29 g per sock. That normalization is useful when another source reports single-sock weight.
Can a 1 mm manufacturer thickness claim be compared directly with a 3.37 mm full-sock reading?
Not without matching the measurement method and location. A selected material zone or single-layer specification is not directly equivalent to a caliper reading through the complete flattened sock.

Conclusion
Among the seven samples measured in this 2026 internal comparison, Zero Give tied HAVO Speed X for the lowest pair weight at 58 g and recorded the lowest full-sock toe and cuff thickness. The measurements support a low-profile construction claim for the tested sample; they do not establish universal superiority in comfort, durability, traction or match performance.
