These guys provide him with shoes, have done for years, generally spiked up trainers or altered cricket shoes

New Balance and Nike especially have been putting their players into new models well ahead of their release to the public. A few years ago Nike had UK based players wearing shoes on TV that you could never buy in the UK, around 18 months before they came out anywhere in the world. It made selling their 'current' range at full price a difficult ask as customers questioned why they were paying full whack when the latest shoe would clearly be out soon.
