I am so in love with these Premium Zoned Cushioned Low Cut socks from Avia®! They fit perfectly! The material has just the right amount of 'stretch' in it to make these socks the perfect choice for me and my active lifestyle. I can walk, run, hike, play sports etc. and these socks move with me without pulling down on my heels or getting twisted up inside my shoes. I love how the stretchy material allows these socks to mold to the exact size and shape of my feet, making for a seamless fit everytime I put them on. The cushioned soles not only make these socks extremely durable but amazingly comfy too. And I love how effectively the extra cushioning absorbs impact while protecting my heels and toes in the process. Plus the cushioning really keep my heels and toes from wearing through the material and causing holes like so many of my other socks unfortunately tend to do. These socks also have excellent arch support. The ribbed material conforms right to the shape of my arch giving me so much needed and beneficial support. The micro-fiber material of these socks has an awesome mesh ventilation that keeps my feet feeling cool and comfortable all day long. And these socks quickly wick away sweat and moisture keeping my feet dry as well. These socks are even made with FRESH HD MAX™ technology that actually works to eliminate stinky odors! These socks are lightweight, breathable and super soft to the touch. They launder extremely well too. They don't shrink, fade or show signs of pilling either. These socks also come in a convenient and money saving 6 pack. And the design of these socks and their vivid colors are super cute and stylish. Avia® is a brand that I've come to love and trust for its visually appealing, long lasting, quality made products and these premium, low cut, women's socks are no exception! Highly reccommended!
