Approving a sample is the last checkpoint before your design moves into full production, which makes it the most important moment to catch anything that needs adjusting. A mockup shows you what the design should look like; a physical sample is where you confirm it actually performs and feels the way it needs to. Here is a practical checklist for evaluating one properly before giving your approval.
Why the sample stage matters
Once a sample is approved, it becomes the reference point the entire production batch is checked against — not the original brief or mockup. This means anything overlooked at this stage is likely to be replicated across your full order rather than caught and corrected later. Taking the time to check a sample properly is a small investment against the risk of receiving hundreds of pairs with an issue that was visible from the very first one. The sample stage sits between the mockup and full production in the standard five-step process, detailed on the process page.
Check the grip first
The silicone grip is the sock’s core functional feature, so it deserves the closest inspection:
- Adhesion. Run a finger firmly across the grip pattern and check that it feels securely bonded to the fabric, with no lifting at the edges of the pattern.
- Pattern accuracy. Compare the grip shape, density and placement against your approved mockup — a dot pattern, wave design, or logo integrated into the sole should match what was confirmed visually.
- Traction feel. If possible, test the sample on the type of surface it will actually be used on (a studio floor, a reformer surface) rather than judging grip by sight alone.
- Consistency across the sole. Check that grip coverage is even, without noticeably thinner or missing patches, particularly if the sole has a custom shape or logo integrated into it.
Check the knit and fabric feel
The base sock itself should match both the material you specified and the comfort level you expect members to experience:
- Hand feel. Does the fabric feel as soft, structured, or premium as intended for your chosen material — cotton, a bamboo blend, or a polyester-heavy performance yarn?
- Stretch and recovery. Stretch the cuff and check that it returns to shape rather than staying loosely stretched, since this affects both fit and how the sock holds up over repeated wear.
- Seam quality. Check the toe seam and any other construction seams for flat, secure stitching without loose threads or puckering.
- Weight and thickness. Confirm the fabric feels appropriately substantial for the intended use — noticeably thin or flimsy fabric at sample stage will not improve in full production.
Check colour against your Pantone reference
Colour is one of the easiest details to approve too quickly, since screen colours and physical yarn colours do not always match exactly:
- Compare in natural light, since artificial lighting can shift how a colour reads.
- Check against your actual Pantone reference, not just your memory of the intended shade, if you supplied one during the brief.
- Check consistency across different sections of the sock if multiple colours are used — the base colour, any contrast panels, and the grip colour should all match what was specified relative to each other.
Check logo placement and branding technique
Whichever branding technique was chosen — jacquard weave, ankle embroidery, or a silicone grip logo — check it specifically against what the mockup showed:
- Placement and size. Confirm the logo sits where specified and at the size agreed, not shifted or scaled differently than the mockup suggested.
- Legibility. Check that fine detail, particularly in a jacquard or grip-integrated logo, has translated clearly rather than blurring or losing definition at the sock’s actual scale.
- Technique-specific checks. For embroidery, check thread tension and that stitching lies flat without puckering the fabric underneath; for jacquard, check that the pattern is evenly woven without visible gaps or misalignment.
Full detail on available branding techniques is on the customisation page.
Check fit and sizing
A sample is also your opportunity to confirm sizing before it is locked in across a full production run:
- Try it on, or have someone representative of your typical member wear it, rather than judging fit visually alone.
- Check cuff height against the model specified — low-cut, mid-calf, or another style from the products page — since fit within a size range can vary by manufacturer even for the same nominal size.
- Confirm sizing works across your expected size range, particularly if your studio serves a broad range of member sizes and plans to stock more than one size band.
Test durability if time allows
If your timeline allows for it, a simple wash test on the sample can reveal issues a single inspection would not catch:
- Wash the sample according to the care instructions you plan to communicate to customers, and check the grip, colour and seams afterward for any signs of deterioration.
- This step is optional and adds time to the approval process, but is worth considering for a first, larger order where confidence in long-term durability matters more than for a small test batch.
What to do if something is off
If any of these checks reveal an issue — grip adhesion, colour mismatch, logo placement — this is the moment to raise it, before production begins rather than after. A sample stage exists specifically to catch and correct these details, so requesting an adjustment at this point is a normal part of the process rather than a delay to avoid. Full detail on how revisions fit into the ordering process is covered in this step-by-step ordering guide.
Approving with confidence
A sample checked carefully against grip, fabric, colour, branding and fit gives you a clear, specific reference for what your full order should look and feel like — and gives you the chance to catch anything worth adjusting while it is still a single pair rather than a completed batch. Taking the time here protects the investment in your full production run.
