The ledger

Claims

8 words carry most of the selling in this catalog. Each has a page. The tag on each one says which of three things it is, and the printed words on the tag say it too, so nothing here depends on telling colors apart.

What the three statuses mean

Defined by a mandatory standard: A published definition that a seller is required to meet before using the word. No word in this catalog is in this category.; 0 of the 8 words on this page
Published method, voluntary: A published method exists somewhere in the world, and nothing obliges any seller to run it or to cite it.; 3 of the 8 words on this page
Marketing only: No body defines this word. There is no method, no threshold and nothing to measure it against.; 5 of the 8 words on this page

All 8 pages

Arch support
18 listings use it
No standards body, trade association or regulator publishes a definition of arch support for footwear, and no listing in this catalog gives it a shape, a height or a test.
Orthotic and plantar fasciitis
3 listings use it
On a footwear listing the word orthotic has no regulated meaning and does not indicate a device made to a clinician’s prescription. This page records the vocabulary and makes no health statement of any kind.
Non-slip and slip resistant
13 listings use it
A published test method exists — ASTM F2913, which measures dynamic coefficient of friction on a whole-shoe rig — and nothing obliges any seller to run it. One listing in this catalog names a standards body; twelve use the adjective alone.
Barefoot and ground feel
4 listings use it
Barefoot, minimalist and ground feel have no published definition and no threshold. No body says how thin a sole must be to earn any of them, and no listing in this catalog gives a stack height.
Memory foam and cushioning
16 listings use it
Memory foam names a material family and nothing else: no density, no thickness, no rebound figure. Test methods for flexible cellular materials exist, and no listing in this catalog cites one.
Wide and extra wide
4 listings use it
Width designations are a long-standing trade convention rather than a regulated system, and they vary between makers. Not one listing in this catalog gives a numerical width.
Water resistant and waterproof
6 listings use it
Published test methods for water repellency and penetration exist and are used across the textile trade. No listing in this catalog cites one, states a rating, or explains which of the two words it has chosen.
Grounding and copper
1 listings use it
This claim has no defined measurement and no recognized standard. This site can neither confirm it nor refute it, and records it here as a word that appears in a listing.
