Well he may not be on the offense, but I sure as hell am. You sir are a fucking moron. There's no such thing as a park boot first off. If so, explain what makes a boot, a park specific boot. Second, you will find people riding in the park tend to like a softer boot for the reason of it flexing a little more than your average boot when you land. Ive seen kids in race boots do cork's. Its the skiier, not the equiptment.
The fact of the matter is every boot fits differently. No feet are the same shape, so ur right u can't buy a boot from online because someone said it works for me. But you can get a general sense of what your looking for in a boot. Back to your statement, the industry needs to develop a park boot, full tilt has park oriented boots aswell as Solomon, dalbello and nordica. There's no "development in the industry of a park boot" because there's no such thing as a park specific boot, that's like asking a mechanic to make your unicorn faster. Impossible.
And the ski industry has stepped its game up for developing park oriented boots. Look how far boots have come in the last 10 years. Now your finding better liners, more durable materials and a lot more money going into boot development. Point and case, my spk, rubber toebox so it will flex if my toe slams into it when I land. You have different boot boards giving the foot more arch support but, so it doesnt hurt, there softer boot boards unlike a race boot which will be stiff for a more responsive feel. Nit onky that but my spk it has a little rubber pad ontop of the boot board to absorb shock from landing. A soft boot is recommended for park because it won't give u shin bang.
Those are characteristics that park skiiers look for in a boot. On that note, go eat a bag of dicks. End of story
