What should i get my 10yo nephew that’s all into radical sports and anything physical for xmas?

Since Ive offered him pretty much everything (under reasonable prices) like all kinds of games, ball games, skate etc, he also has a bike so I’m totally out of ideas

last gift was a cheap xiaomi sports bracelet which he loved, but now I don’t know how to up it…

A pair of socks? He only shows much love for me near the seasons 😂 so I told him santa was watching (of course he doesn’t believe in santa anymore). I might prank him but I need a backup gift, so… title
