Swiftwick Flite XT Five Socks

About Swiftwick

Swiftwick bases their business on three principles: Adventure, Commitment, and Technology. Their Best Sock Guarantee: “We are committed to providing each customer the best experience possible. If you are unsatisfied with a Swiftwick product, reach out to us and we will take care of you.”

Socks are something that you shouldn’t have to think much about when you are wearing them. They should only enhance (protect, comfort, support) not detract from the enjoyment/performance of the activity they are being used in.

I’ll review these socks under three criteria: comfort, durability, and performance.

About the Flite XT Five:

The Swiftwick Flite XT socks are specifically designed for cross-training. Swiftwick claims that they are “the most technologically advanced cross-training sock ever developed.┬áThe socks feature designs and technologies for activities where the foot experiences frequent lateral movement.

Initial fit and comfort for the socks when I first tried them on was outstanding.The sock has good compression which feels uniformly comfortable in the forefoot, midfoot, heel, and ankle. I have flat feet, and often times specialty socks, compress my collapsed arch too much and cause my feet to cramp. I don’t get the sense that will happen with these socks, but I will make sure to note it in my next update.

I wear a 10.5 shoe and so I went with the Large according Swiftwick’s sizing chart. The Large fits my foot well and the Grip Dry ankle cup doesn’t ride too low or pull too high up.

Planned Use

I am currently in the early training stages for a 50k trail race in September. While these socks were designed for cross-training, I plan on wearing them during my runs. I also plan on wearing the socks while doing Crossfit workouts as well as hiking and backpacking.

Check back in about a month when I report back with my initial update on the Swiftwick Flite XT Five socks.

Thanks to 4AllOutdoors and Swiftwick for the chance to review these socks!
