Dick's Sporting Goods offers the PUMA Men's Ignite Flash evoKnit Training Shoes in Black or Black/Grey for $29.98. Opt for in-store pickup to dodge the $5.99 shipping charge. That's the lowest price we could find by $10. (We briefly saw it for $18 three weeks ago.) They're available in sizes from 7.5 to 13.
