Wish I'd seen those years ago. I've had a number of shin bumps over the years I've padded with donuts cut out of stick-on foam.
They usually disappear over the summer.
This.
I have had shin lumps appear at the beginning of a ski season and disappear within one/one and a half month at the end of it. Every year for the past, ahem, decades (at least since the advent of plastic, shin high ski boots). I simply took it as a by product of the skiing activity and rode on. Some years were more painful than others, especially at the end of a season, some years, just a shin lump, something that was there and that was all.
Now, about two seasons ago, I have changed my way of skiing and...no more shin lumps...some discomfort sometime, but no lump. I am also skiing in softer boots, and that might be part of it, but not all, since also at least one other guy I ski with has also changed the way he skis and has noticed the same phenomenon and still skis in a stiffer boot.
I, again, took it as a sign of the fact I was pressuring the front of the boot correctly, but it looks like I must have not been, for all these past years, since...
It appears that I now pressure differently the boot tongue, more gradually, not constantly while still "driving forward", and at a different time of the turn, as a result...no more lump.
