Hirscher's cleaning up on the World Cup, because his boot set up has come right for the first time in 4 years. He has always had this kind of talent and skill, but without the boots just right he has to adapt like anyone else. Because Hirscher is so good and so much better, he was still able to set records, but now that everything is right, no one can touch him. Now that he has all of his prowess available to him he looks unbeatable.
For me personally, it was very frustrating to watch Hirscher the last 2 seasons, because I knew he was a better skier. I kept quite while everyone was raving about Kistofferen, he's not perfect and he's not as clean a skier everyone wants to make out. I know Hirscher won two overall world cups in this period, but he's even better then that. However, just like with Mikaela Shiffrin and others on Atomic, there are mistakes with their boots. Head has mistakes with their boots as well. Look at Alexis Pinturault it has taken Head and their Team almost 4 years to get his boots working. Now he's starting to ski like he can. If you know this and watch the struggling skier making adaptive movements because of the boots; because they are not able to use their natural technique, it's very frustrating.
