A little heel slip (for boots) is normal, especially when boots are new. Typically, as the sole breaks-in and becomes more flexible the slippage will decrease. I simply use thicker socks. Merino wool hiking socks like Smartwool or LLBean Cresta have a thickened heel and a little extra padding on the bottom. Also be sure the forefoot laces are tight enough.
