While running errands around LA (on more than one day in a row), Jennifer Garner showed off her brand-new shoes: these Isabel Marant Basley black suede tassel booties ($600), which also come in camel and white. At first glance, we thought they were high-top sneakers, but upon closer inspection, we realized they're actually a cross between a sneaker and a bootie — genius! While the price tag is rather steep, we think these booties are worth the investment for a few reasons. First, they're by Isabel Marant, so they're automatically cool in our eyes. Second, they look super comfy. And third, they might just be the new shoe trend of the year (stay tuned). Side note: we also love the way Jennifer wore her new shoes, with a boyish blazer, a plaid blouse, skinny jeans, and a white scarf. All in all, it's a head-to-toe outfit win.
