If Hayley Williams tells us a fall shoe trend is chic and actually comfortable, we tend to believe her. If there’s anyone who’s qualified to make such a statement, it’s this busy wellness and fashion TikToker whose daytime nannying gig takes her all over New York City. She requires a shoe that’ll see her through an average workday, which involves creating new content, trying new workouts, checking out new coffee shops, and going on mini adventures with the child she nannies. This fall, her boot style of choice is a chunky platform with a ’90s edge.

“Boots are such a necessity, especially when you live in the city and your main way of getting around is by walking,” she says, professing her love for Sorel’s versatile lug-soled sneaker boots. “I love a good chunky boot that can be versatile in terms of dressing up and dressing down—they’re comfortable and appropriate for any weather.” Read on to see exactly how she’s styling four of her favorite pairs just in time for the chillier temperatures rolling in right about now.

Williams built this sporty yet polished ensemble around these chunky Sorel sneaker boots. “They kind of remind me of a ’90s sneaker,” she says of her go-to fall shoe, which she’s expertly paired with a cropped white tee, black dress pants, and a waistcoat. “I’d wear this look out to dinner with a cropped jacket.”

“These boots are such a good neutral staple,” Williams says of this Sorel style she keeps in constant wardrobe rotation. Here, she’s styled them with a full-length black dress and a sleek, slightly retro-inspired leather blazer. “I’d wear this look to go out and about or even to nanny for the day,” she explains of this truly versatile outfit formula.

Frankly, running errands around all five boroughs has never looked chicer thanks to Williams’s black bodysuit, cozy wrap sweater, and versatile boots. “When you’re putting together an outfit to wear all day in the city, adding a sporty element and combining it with dressier accessories provides the perfect mix of comfort and class,” she explains.

“I don’t really have a particular aesthetic, but I do lean more toward street style–type outfits,” she says of this fun ’90s-inspired look complete with light-rinse overalls, a knit crop top, a cropped cashmere sweater, and a mini handbag. Her parting style tip? “Play around with size and proportions!” she advises. “Working with different shapes can really make or break a look.”
