Our pool area has stamped concrete around it. We've tried adding grit to our sealer and have used a special sealer with grit in it, but it is still dreadfully slippery. It also gets so hot in the summer we can't walk outside to the pool without shoes on. Can anyone suggest a product to apply or another creative solution to make our pool area more enjoyable?

To answer your question. If the stamped cement has been painted you need to use a light color. Other then that, your out of luck. Also any cement surface regardless of color will be hot in the sun. The finish should have been a broom finish. I am surprised that the sand type of finish textures did not work.
As far as anything else to help prevent slipping. Other then sand finish sealed into the cement, which the sealer itself will make it more slippery. No ideas.
