Dynafit TLT's; snow packing in front of heel piece

Apologies

Be careful, Larry, it's illegal to ski in Germany or Switzerland without the "Technischer Uberwachungsverein" logo showing plainly! 

Can't really say I've had a problem with snow sticking in that location - usually it's between the toepiece and my F1 shim under the toe when I forget to hit it with silicone spray for a while.

Silicone spray does the job for my wife's comforts, at the toe -- I imagine it would help for the heel.

I think the problem has a lot to do with not only snow conditions but with the amount of clearance at the heel. Some skis I use are worse than others in that regard. The fortunate thing is it is less of a problem with the heel stepped up one or two positions. Unfortunately, that doesn't help on low angle terrain.
