The perfect socks
1 of 1 people found this posting helpful
Review by Carter on Feb 12, 2016
Swiftwick customer service helped get me into the Aspire Four socks, and they are absolutely perfect. They provide just the right amount compression and moisture management while I am running or cycling. I loved my initial pair so much that I decided to buy 3 more pairs.

Because of Swiftwick's excellent customer service, they have turned me into a customer for life.

Great support for Achilles tendon

Aspire Four is a great addition to your sock wardrobe as it offers extra support and warmth for the Achilles tendon and protects ankles on trail runs. The Aspire line of socks is literally all I wear for running 60+ miles per week during marathon training.

Great socks
  Review by Lawrence Crane (Florida USA) on Oct 09, 2015

I have had a lot of trouble with a collapsed arch swelling during a bike ride and causing me to be unable to go more than a couple of hours. These socks have given me at least another hour pain free if not more as the longest ride I have done is about three hours.

Why did I wait so long to try.

Swiftwick for life
  Review by Max Cooper (New Hampshire USA) on Aug 10, 2015
I needed a pair of socks for the Spartan Race Sprint in Fort Carson, CO because like an idiot I forgot to pack socks... Anyways I walked into a local running store in Colorado Springs and came across these Swiftwick compression socks. Hadn't heard of them before, but the owner swore by them. General rule of thumb, never wear new to a race, but I didn't have a choice. No blisters, no scrunching, these socks were glued to my feet. I haven't trained or ran a race since without my Swiftwicks.

Best Socks on the Market
  Review by Matt Maher (Missouri USA) on Aug 07, 2015
The reviewer has last purchased this item on Mar 29, 2016
By far the best socks I have owned. I do not ride with any other socks. They are great for road, MTB, and cross. The socks fit like a glove and keep my feet dry. I love the varying heights available including the TWELVEs. The compression they offer is great without being too constrictive.
