I'm a big fan of the athleisure look for two reasons: 1. It's comfortable. Who doesn't want to live in sneakers and cashmere sweats? 2. It's elevated the "off duty" look and pushed brands to create more stylish options i.e. sneakers and loungewear. You can invest in a pair of sneakers like these (I own them and after 3 years can attest to their comfort!) and throw them on with jeans and a cozy sweater and you're good to go any day of the week. I also love this pair on sale. If you only want to purchase one pair of sneakers this year for the gym and beyond, I found this pair which has a color palette that lends itself to both looks (and UNDER $50!!).
Recently I've been stepping it up a notch and wearing my sneakers with leather leggings. The ones I'm wearing are old but I found this similar (lighter) pair and also this budget friendly vegan pair (I haven't tried these yet but they've become a favorite amongst bloggers this year). Updating my new year's resolution: wear comfortable shoes, i.e. sneakers at least three days a week!
