One pair. Trimmed once. It still fits the shoe.
The most common reason an insole gets thrown out isn't comfort — it's that it fills the shoe. GOLIATH runs 4.0 mm at the forefoot and 18.3 mm at the heel. That's a medium profile: enough structure under the heel, almost nothing under the toes, which is where a shoe runs out of room.
Top — the face you see
NanoSpread™
The textile your foot touches. It moves moisture outward by channel geometry alone — no coating, no energy, nothing to wash out.
Profile — the wedge
4.0 mm to 18.3 mm
A blade at the toe rising into a deep heel. Structure where a foot lands, almost nothing where a shoe runs out of room.
Underside — where the systems sit
Four zones
- LeapCore™ — the teal body. It doesn't cancel the load, it redirects it off the centre and out across the rest of the surface.
- ThinBoom™ — the recessed forefoot pad. Supercritical E-TPU: it yields and spreads the load.
- Arch System — the navy shell. Stiffness, not cushioning.
- PORON® XRD® — the yellow heel zone. The faster the impact, the stiffer it answers.
Zone positions come from the GOLIATH zone drawing. No performance figures here: the ones that exist are properties of a material, not of the finished insole.
And they look like something in all of them.
Nobody buys an insole because it's good-looking, and the corpus of what people actually say backs that up — they buy to get through the day. But they do say they'd rather not be seen wearing an orthotic, even by the person selling them shoes. Between two that work, the one you don't mind looking at wins. That part is our bet, and we're calling it a bet.
Trimming is where this category quietly fails.
Almost every trim-to-fit insole is cut from the toe. Which means the arch stays exactly where it was, and on a smaller foot it now sits in the wrong place. People report this constantly, and it is the most likely reason no product in this category is rated above 4.6.
What everyone does
One cutting line, printed once, identical on both insoles. Cut from the toe, hope the arch still lands right, and once you've cut too much there's no going back.
What we do
Left and right are not the same insole and they don't carry the same marks. The guides are printed per foot, on the underside, and the pair is asymmetric by design — it's why the two halves only complete the frog when they're together.

The return terms for a trimmed insole. Superfeet takes them back at 60 days even cut; Currex refunds cut insoles without questions. We match the category or we say so — this block ships with the exact window and coverage, or it doesn't ship.
