I have Keos. I like them...but I often get a bad hot spot in my right big toe. Having read about a zillion threads, here and elsewhere, on hot spots, I can tell you that there's no one solution to them...or any solution for that matter. There are a lot of things that seem to be a factor: shoe width, insoles, pedaling technique, cleat placement, pedal system, and biomechanical issues, e.g, leg length discrepancy. Just to name a few.
I've tried nearly everything with no real success. I get by on wearing very thin socks and appying Tiger Balm every 20 miles or so to my big toe.
If I were you, I'd start by changing out my insoles. I use esoles, but lots of people have found success with Specialized Body Geometry insoles. Did you have a shop actually "fit" your cleats or did you use put them on yourself? If it's the latter, you might find a good fitter in your area and make sure you cleats are where they ideally should be.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
