Nothing beats the feeling of running or biking outdoors - the fresh air, soft breezes, and beautiful scenery make you feel so energized and alive. Now that the air temperature is heating up, you're going to find that as soon as you step outside, you're going to begin to sweat.
I'm sure you're sporting a wicking sports bra, underwear, and tank top, so what about your feet? They're stuck inside your sneaks, and they probably get more hot and sweaty than the rest of your body. You need a good pair of socks that will wick moisture away from your feet, so you can stay dry and prevent blisters.
When you're active, cotton socks just don't belong on your feet. There are plenty of options that are just as soft but the material will keep your feet more comfortable when they get hot.
These are one of my favorites made by Darn Tough called the Back Road Series. They're made with 71% merino wool so they wick sweat away from your skin and into the wool fibers. The heel and toe are reinforced where you need it, and there is elastic support around the arch. I also love the mesh knitting on top of the foot to keep your tootsies even cooler.
Fit's Tip: You can order them from backcountry.com for $12.95. They're more expensive than your basic cotton sock, but they'll last longer and keep your feet cool and blister-free.
