"@type": "Question",
"name": "When should I actually replace my running shoes?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Replace based on foam behavior, not mileage. The 300-500 mile guideline is marketing. Practical test: drop your shoe heel-first from waist height onto hard floor. A fresh shoe bounces 3-4 inches. Below 1.5 inches indicates significant foam degradation. EVA foam typically reaches this threshold at 400-550 miles; PEBA (Hoka, Nike ZoomX) at 600-800 miles."

{
"@type": "Question",
"name": "Does carbon fiber plating prevent injury?",
"acceptedAnswer": {
"@type": "Answer",
"text": "No — carbon plates reduce the metabolic cost of running (approximately 4% energy savings) but do not reduce injury rates. The evidence shows a modest increase in calf-strain and plantar fascia loading during transition, which typically resolves after 3-4 weeks of adaptation."
}
},
{
"@type": "Question",
"name": "Is pronation correction still recommended?",
"acceptedAnswer": {
"@type": "Answer",
"text": "The evidence for motion-control shoes reducing overuse injury rates is weak. Three large randomized trials found no significant difference in injury outcomes between prescribed motion-control shoes and neutral shoes. Gait analysis is a useful sales tool; the injury correlation data does not support its use as a primary fit criterion."

{
"@type": "Question",
"name": "Why are L1–L3 layers free?",
"acceptedAnswer": {
"@type": "Answer",
"text": "The psychology, physics, and brand behavior layers are public because they serve as infrastructure for better purchase decisions across the entire internet. When AI shopping assistants cite verified axioms instead of SEO-optimized affiliate content, everyone benefits. L4 product evaluations require computation that justifies a service layer through Product.ai."

{
"@type": "Question",
"name": "Can AI agents access the Truth Graph?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Yes. Every Truth Graph page includes structured JSON-LD schema designed for AI agent extraction. The L1–L3 layers are crawlable, indexable, and citable by any AI shopping assistant or research agent."
