Replying to New boots make my feet numb

I just bought some new boots after five years of riding boots a size too big. They fit awesome, clamp down on my shins perfectly and really feel like an extension of my legs. First day riding and my feet are numb after a few runs. My old boots didn't do that, but they were a size too big. They are the salomon s/pro 120. Do I need to nut up and tough it out for a few days to break them in, or is this abnormal? I have never had new boots before so looking for advice.
