Traffic
Traffic: model names, versions and the spec comparison
Runners search by model and version, then by spec and purpose. The name of a shoe plus a version number, that shoe versus another, stack height and drop for a stated purpose, best shoe for a marathon on a training plan. Triathletes add wetsuit thickness and buoyancy queries, and race-specific searches. A store that lists the current version only, under a Shoes collection, loses the version comparisons and the runners who loved the previous version. The traffic work is a page per model that persists across versions with the changes written out, spec-led collections by stack, drop and purpose, and race and training content that links to the shoe the plan calls for.
