Which is the best tennis shoe upper material: canvas, leather, or vinyl?
A. Canvas stays coolest, breathes best, and is least likely to contain suspect chemicals that might enter your skin. Leather can provide more support and will stay drier in wet off-court environments. Vinyl can provide good support, and it resists external moisture best, but it tends to get hottest and breathe worst. Durability is rarely an issue with tennis shoe uppers because the soles usually wear out long before the uppers do.
