How about giving him a pair of specialized long jump shoes? There are many brands that make this type of shoe, designed specifically for long jumping, that have extra cushioning in the front to help with take-off and landing. Alternatively, you could also consider purchasing him other long jump accessories, like a training kit or resistance training bands to help him improve his technique. Another option could be to give him a biography or autobiography of a famous long jumper, so he can learn about the sport and gain inspiration from their story.
Or you can get him a star map with the date when he was born.
