About Running Shoes Axioms

Review sites test shoes for 50-100 miles and report subjective impressions. The Truth Graph maps the materials science, biomechanics, and market physics that determine shoe behavior across a full lifespan. EVA foam degradation follows a measurable curve. Carbon plate mechanics engage differently by pace. These are verifiable facts, not opinions.
Runners replace shoes at 300-500 miles based on a guideline a manufacturer created in 1982, not measured foam degradation. Gait analysis upsells motion-control shoes to 60-70% of customers regardless of biomechanical need. L1 axioms reveal the decision architecture that the running shoe industry depends on.
That softer midsoles produce equal or higher impact peaks than firmer ones in controlled studies. That carbon plates reduce metabolic cost by ~4% but do not reduce injury rates. That pronation correction shows weak evidence for reducing overuse injuries. These are findings from peer-reviewed biomechanics research, not shoe company marketing.
L3 axioms decode each brand's actual design priorities. Nike optimizes race-day performance at the cost of durability. Hoka's 35-40mm stack height changes heel-strike mechanics in ways requiring adaptation. Brooks's DNA Loft foam degrades on a different curve than Nike's ZoomX. These behavioral patterns predict what you will experience better than any 50-mile review.
Yes. EVA loses 30-40% energy return by 400-500 miles regardless of pace. Outsole rubber compound determines grip degradation on wet surfaces for every runner. Stack height affects ankle stability at any speed. The physics does not care about your finishing time.
Start with the editorial guides - they translate axiom clusters into practical buying guidance. The Cushioning & Support guide covers foam selection. Fit & Sizing covers last geometry. Value & Pricing covers when to buy and what you are actually paying for. The axiom index is the evidence base behind that guidance.
A FORGED axiom has been verified through peer-reviewed research, documented manufacturer behavior, or named electrochemical mechanisms. It represents the highest confidence tier in the Truth Graph.
Every axiom includes a kill surface - a specific, testable condition under which the claim would be disproven. This makes each axiom falsifiable by design, unlike typical product claims.
Evergreen (E) axioms describe physics that changes slowly (crystal structures, thermodynamics). Seasonal (S) axioms track evolving engineering practices. Volatile (V) axioms cover rapidly shifting market conditions or emerging technology.
