Boxer briefs riding up, need real solutions that actually work

Every pair of boxer briefs I’ve tried seems to ride up no matter the brand, and it’s honestly becoming annoying. Feels like every time I take a step they bunch up, and I end up constantly readjusting.

I’m specifically looking for boxer briefs with a longer inseam and a fit that stays in place, ideally ones available in the UK. It’s not just about comfort, a pair that consistently stays put makes a huge difference during the day, especially when you’re active or moving around a lot.

Would love to hear about what people actually wear that doesn’t keep riding up, not generic suggestions but ones that have actually stayed comfortable all day.
