Rating 5 stars because I want this company to succeed, but in reality probably closer to 4.5/4 stars, as there is room for improvement!
First and foremost, the socks are very comfy! However, these wouldn't be socks I'd personally try to do anything active in, which is expected and completely fine, given its composition of 95% cotton and 5% spandex and branding of "Everyday" socks.
During my initial wear right out of the package, I thought the cuff would hold the sock up well. I was also hoping the sock would shrink a little in the wash, as it felt like it skewed toward the larger end of its sizing range than the smaller end.
After a few washes and wears, I find the sock slips down a little too much for my liking; the toe pockets are the perfect length; and the bridge feels a little short (sock doesn't seem perfectly aligned with my heel even though I have the sock pulled all the way up). These socks are very easy to take off, so ironically, maybe they keep my feet too dry and breathable?
These socks don't fit as well and aren't as functional as Injinji and Tabio, but the whole reason I decided to buy MARO is because I was looking for toe socks that contained as little synthetic fiber as possible. These socks definitely achieve that goal, and I've very satisfied with my purchase!
