Our Dedication Lasts a Lifetime

Our goal is to ensure that all our customers are 100% happy with their purchase. We want to make sure that you are running and reaping the benefits our socks offer. This is why all Rockay Socks come with a lifetime guarantee. If your sock tears or lacks basic functionality, we will send you a new pair of socks.

We designed the Rockay Sock from 66% Polyamide, 30% Organic Merino Wool, and 4% Elastane. Each material was carefully selected thanks to their unique cushioned benefits and compressive nature. Eventually, the Rockay Sock will be manufactured from 100% recycled materials and polyester from plastic found in the ocean.

A Touch of Comfort for Enhanced Performance

Each running sock is carefully designed from the utmost comfortable materials that also promote breathability to empower each runner’s performance and experience.

With the inclusion of Organic Merino Wool, the Rockay Sock will work to ensure your feet are always ready for peak performance. This material ensures the optimal temperature for both warm and colder environments, which helps in the prevention of blisters and chafing. The material also creates a compression-fit, which assists in protecting and supporting a runner’s foot and arches to minimize injuries and even the discomfort of plantar fasciitis.

In addition to this, we also included thinner zones, which were strategically placed and designed for each Rockay Sock. This is meant to enhance the sock’s natural ability to provide ventilation and breathability to the most crucial parts of the foot.

A Reliable friend – mile after mile

All runners know that hot weather, moisture, or constant friction are some of the biggest disadvantages that we face. Instead of making enemies, Rockay is focused on making friends. This is why our product will work effortlessly to keep your feet cool, dry, and free of any irritating ailments, like blisters or chafing. In fact, we even carefully designed the heel tab to elegantly blend with the ankle cuff as it promotes a more comfortable running experience. Typically, running brands separate this, which often results in chafing.

Happy piggies

Great sock! Best I have worn in 44 years period. Please make more color option(s) like pinks, reds, purples. Brighten it up a bit cause I want to buy lots more..:) But they gotta be colorful. Thanks a again for a well designed product full of comfort and support.

Great product

I probably should have ordered the crew because my feet are size 15 and the largest size isn’t quite big enough for that size to fully cover the back of my foot where my running shoes contact the skin.

That said, these are still significantly better than any other running sock I have used. I highly recommend these socks and if they ever add a larger size, I’ll probably order a half dozen of them.

That said, they still function much better than

Great Sock

What a wonderful sock. I ware a size 10.5 the large fit great. I was having trouble with my feet sweating, this sock stopped all problems. The design of this sock really helps keep it in place on your foot. Not to mention it is extremely comfortable. Highly recommend.

Love them!

I got these socks for free via Stride Box, and I really love them! They are generous in the right places (toe box) & supportive in the right places (arch, fascia). They are high enough that they don’t disappear into my shoe, but not too tall. They stay put during running, look great, and don’t beed to be fussed with during my run. Thank you for the awesome socks, & I will definitely buy more.

Love these!

I’m not a runner but I love these socks. I mostly walk but do intervals with running or jogging. I really need to pamper my feet because I just have bad feet. It’s genetic. Both my sister and I developed bunions in grade school. Anyhow, I need arch support and these socks have that. And cushion. Super comfy and supportive. I found the size guide worked for me as well. I wear a 37 in european sizing and about a 7 in US and the smalls fit perfectly.

ByDiana C. verified buyerfrom Lincroft, NJ, US

Love these socks!

I’m pretty resistant to change. I’ve been using the same brand of running socks since my high school track days, which were longer ago than I’ll admit here. But my husband convinced me to give the Rockay socks a try, and I’m glad that he did. They give my feet just as much support as the other socks, but they’re like half as thick (so twice as comfy!). I was sold after my first run. Will definitely be ordering more.
