I don't know for certain that modern Harlicks need to be Snow-Sealed. If you think there is a varnish, call them and ask. Maybe they will suggest something more durable.
BTW, I think Snow Seal is just Bee's wax. which you can buy in the candle section of a craft store - but they may have added a solvent like oil to drop the melting point a bit.
BTW, your blade covers are very pretty!
It is very hard to tell from the picture, but it almost looks like there is a line where you scratched each boot with the other blade above the outsole as well. If so, I don't have a fix for that.
A lot of ice dance coaches advocate the "neat feet" concept, where the boots touch each other, or almost touch each other, as they are along side each other or pass by one another, so little scratches may be inevitable.
I also can't quite tell from the picture, but it sort of looks like there is space between the outsole and the blade mount plate near the toe. A good fitter would usually normally put a "shim" in between, to take up the space and equalize pressure, so the blades don't gradually warp or twist. Did he/she? Is the same true of the outsole/mounting plate in the back? (With those blade covers, your blades are quite modestly attired, and chose quite primly not to show their back sides in public.
Perhaps they will be a little less modest on the ice.
