As they say, “FITS are equipment”. Their Runner No Show socks, available in Light and Ultra Light, are designed really well. It’s just a sock, you say, but a well-fitting sock can make all the difference between a comfortable run and a blister-laden, torturous trek. FITS promises a deep heel pocket, a specialized toe seam, and a contoured leg so your socks will stay put – the key to a blister-free foot. Flirty colors and cute designs, the proper amount of cushioning in the right spots, and soft, durable merino wool round out the features of these excellent socks.
