How Each AI Assistant Handles Shoes Footwear
Amazon Rufus
Rufus treats sizing accuracy as gospel. It scans thousands of reviews for phrases like 'runs true to size' and 'order half size up.' Products with consistent sizing feedback get priority placement. For athletic shoes, it asks about your activity level and checks review mentions of durability. It heavily weights recent reviews over old ones and flags products with high return rates.
Rufus suggested New Balance Fresh Foam shoes, citing 89% of reviewers saying they run true to size and specific mentions of wide-foot comfort. It flagged that Nike options tend to run narrow based on review analysis and recommended ordering up half a size for Adidas alternatives.

Weaknesses
- Limited to Amazon inventory only
