Stars are booting up in gray boots of all heights. Both Hayden Panettiere and Jessica Alba were spotted in the stacked-heel Maxene boot from Coach. "[Our customer] wants pretty, spirited fashion," Coach creative director Reed Krakoff told In Style. "So we went for playful and desirable." The neutral shade makes for standout footwear that can blend with jeans and basic black alike. Or, think Kate Hudson and go charcoal from head to toe!
