I'm trying to install retrotreads (or simpletreads) over my stairs, but I've run into some serious issues. Our stairs are really crooked and warped, which we expected, so we planned to shim under each tread. However, getting everything to fit right is turning out to be way more complicated than we thought. Is there a better technique we could use? Also, we've decided to let the treads acclimate inside as a first step—any advice on what to do while we wait?

Are the four steps in your photo the entire staircase? If that's the case, shimming them may not be worth it since it sounds like just a facelift. Honestly, consider selling those tread caps and replacing the whole setup. Pull the old carpet, then shim the stringers to get everything up to code (it's easier than it sounds!). Installing new hardwood treads could be done all in one day depending on skills and tools. It could really elevate the look!
Totally get it! For those warped stairs, shimming can work if you’re using retro treads, but it's tricky. I suggest trying to shim them while they're acclimating. If they really won't fit right, consider replacing the tread entirely—it might be easier than fighting with the shims. From the photo, they look like they could be swapped out, but I know that depends on your setup.
Hey, I hear you! Definitely stop what you’re doing and follow the manufacturer’s instructions to let the treads acclimate. When I was renovating my own stairs, I found the same problem with warped steps. I had a pro finish the job, but I had to prep everything first. It involved tearing out the old carpet and rebuilding a few things. It can be a hefty job, but trust me, checking the prep work can save you from squeaky stairs later on. Just take your time with this!
Yeah, tread carefully! Ha!

There's actually six steps, not just four! I haven’t heard of a ‘stringer’ before and we don’t own a miter saw either. Wouldn't it be simpler to fix the current base steps and just put these nice oak treads on top?!
