Replying to Breaking Salomon SPK boots in...

I bought a pair of new 27.5 SPK's about a month ago, and have skied them twice (it hasn't been more cause I live in central california, and snow is lacking right now.)

Anyways, its been about 8 hours on the hill so far, and the first day my foot was totally numb, and hurt pretty bad, but i expected that cause I bought them snug, and fit well.  The second day was much better and they feel like there breaking in, but they still feel rather tight.  How long does it take for boots to break in fully and form to your feet?  I want to be able to enjoy my boots :)
