So at the start of this coming season, I'm gonna buy some new boots. However, I just realized that the times I've bought boots before it's generally been mid season.

Could be a dumb question but are you more likely to get a better fit when you've already been in boots for a few weeks? Are your feet different after a summer of flips flops and loose fitting shoes?

In short, should I ski for a week or so in my old boots before I get new ones to ensure a better fit?
