[5] In the spring of 2013, Spira was selected to be featured as part of the A&E Networks Project Startup, and initiative with the crowdfunding site RocketHub to raise capital for a new lightweight running shoe.

The company will introduce a running shoe that will feature the signature duck camouflage pattern sported by the Robertson family, who are the stars of the reality television series.

The study measured oxygen consumption and heart rate at a pace of 11 kilometres (6.8 mi) per hour to determine the energy output of each runner.

[10][11] Spira claimed that their shoes were banned from races because they purportedly did not conform to International Association of Athletics Federations and USA Track and Field standards.

Axel Zeebroek used racing flats in the running portion of the triathlon and Franklin Tenorio of Ecuador and Joao N'Tyamba of Angola both ran the marathon using Spira shoes.
