Sidi Soles packing full of snow - tips?

CXers in general, Sidi users in particular, any tips on what to do in snow w/running? Never had shoes pack up like this before. Crazy. Have raced cx for the past 5-7 years, live in Northern VT for the past 15 odd years, so I know snow. But first year w/Sidis and I get the attached result during the morning's intervals.
