SPOX V2 Runner – World Record Edition

PLEASE NOTE: THIS IS A PRE-ORDER.

The pre-order window runs for two weeks, from 19 August until 2 September 2026. Once the pre-order closes, the socks will be ordered and are expected to arrive and be posted to customers at the beginning of October. £2 from every pair sold goes to the official charities. 

WORLD-RECORD-BREAKING PERFORMANCE. ZERO BLISTERS.

This isn’t just another running sock. It’s the sock worn by David “Jacko” Jackson as he broke the Guinness World Record for the most consecutive daily ultramarathons by a man—completing 81 ultramarathons in 81 days and continuing towards an incredible 100 in 100 days. Now we’ve decided to launch one for you to wear with all the exact same premium construction. £2 from every pair sold goes to the two charities Jacko is supporting. Headway UK and Head for Change. 

Across thousands of kilometres, David completed every ultramarathon without suffering a single blister.

Created using our premium SPOX V2 Runner construction, this special-edition sock combines cushioned toes and heels, supportive arch compression and a soft, breathable performance knit designed for serious mileage. The thicker V2 design provides lasting comfort and protection without feeling bulky, whether you’re running an ultramarathon or your first 5K.

Finished in mint green and white with David’s MISSION IN-POSSIBLE design, these socks represent determination, resilience and the belief that our limits can always be pushed further.

If they can help carry David into the record books, imagine where they could take you.
