Running Shoe Multi-Brand Catalog Scraper

Scrape running shoe catalogs from Brooks, Saucony, Altra, and On — four premier running-specialist brands — all normalized into a single dataset. Built for affiliate publishers, competitive-intelligence teams, and shoe-recommendation engines that need structured spec data beyond what generic shopping scrapers offer.

What it does

Crawls Running Warehouse's per-brand catalog pages (the cleanest, most open source for all four brands) and extracts runner-relevant technical specs from each product detail page:

• Biomechanical specs: heel-to-toe drop (mm), heel stack height (mm), forefoot stack height (mm), weight (g)
• Product metadata: SKU, model family, generation, product URL, MSRP
• Catalog info: available sizes, in-stock status, star rating
• Context fields: gender (men/women), terrain (road/trail)

Input

Field	Type	Default	Description
maxItems	integer	10	Maximum shoe records to return
sources	array	["brooks","saucony","altra","on"]	Which brands to scrape

Example — Altra only

{
  "maxItems": 50,
  "sources": ["altra"]
}

Example — all four brands

{
  "maxItems": 500,
  "sources": ["brooks", "saucony", "altra", "on"]
}
