Kalenji is a sporting brand who became known in the free running and parkour communities for their Kalenji Success shoe, which was the shoe of choice among many free runners due to its cheap price and impressive grip.
 Kalenji Success
The Kalenji Success was a shoe which became one of the most commonly worn shoes in the free running community by late 2008. Available from Decathlon for £9.95 and with impressive and durable grip, they spread quickly and became the shoe of preference for many free runners.
On April 10, 2009, Tim Shieff created a Facebook group to announce that Kalenji had stopped production of the Success and replaced it with a newer model with grip that quickly tore up. The situation was dubbed as the Kalenji Crisis, and as word spread among the free running community, the group soon reached over a thousand members.
Efforts to bring the shoe back included a photo petition, with several hundred photos sent in, and contacting Decathlon or Kalenji directly to complain. The company confirmed that the design had indeed been updated, and the name changed to Kalenji Ekiden 50. It was soon backed up by many people who tried the new model of shoe that the grip tore up much faster than the Success'.
Scott Bass took the initiative to take the contact with the company further, and successfully got them to agree to produce a limited run of the shoe if there was enough interest. He set up an online data collection form to gather information about the volume of interest, and is still trying to create an agreement with them, but is having trouble due to bad organisation on Kalenji's side.
In July 2011, a new version of the shoe was announced, dropping the Kalenji branding and simply being labelled the Success. The shoe only features slight changes to the original model, and is set to retail in Decathlon UK stores in December 2011 for £16.99.
