Chicwish has quite a lot of models as this one, cozy, with a turtleneck and long sleeves, so they are just between a very cozy knitwear and a perfect poncho.
If you're considering buying a pair, opt for black, because they're timeless and you'll have no trouble styling them with things you already have. Once you decide on a pair, avoid styling it with a leather jacket, because the look will be too heavy.
There is no rule stating that you can only wear high top sneakers to the grocery store or a walk in the woods; you can even opt to wear them with a dress (long and short), cropped pants, elegant suits and, of course, jeans.
