My new wool hiking socks keep slipping down inside my boots—any hacks to keep them up during long treks?

I just bought a pair of merino wool hiking socks that are super comfy and breathable, but after a couple of hours on the trail, they keep bunching up around my ankles inside my mid-height hiking boots. I've tried adjusting my boots tighter and even folding the socks differently before putting them on, but no luck so far. I really want to avoid blisters and discomfort on my upcoming 3-day hike, so having socks stay put is important. Has anyone dealt with this sock-slipping problem before? Are there specific sock brands or styles with better grip? Or maybe some tricks like adding elastic bands or sock liners that actually help? Would love to hear what’s worked for you!
