A couple more ideas:
If you are ripping up your fingers pulling the laces tight, get lace pullers! If your shoe store doesn't have them, try eBay. I trust, BTW, that you are pulling the laces tight all over, starting from the bottom lace holes, and locking each layer by putting fingers over each pair of holes while you tighten the next layer. (But not so tight that your feet go numb.)
If there is any space inside the boot (places where the boot isn't tight around the foot), fill them with moleskin or other adhesive foam. (Though I'd never want the toes too snug, as the doctors talk of bad medical things that happen to too snugly fit toes.)
A lot of freestyle skaters and hockey players want extra space in front of and behind the ankle on top, so they don't have to bend their super stiff boots when the flex and point. There is no consensus, but a lot of people in softer boots want it snug all over - just like you would like in high top tennis shoes (but much snugger than tennis shoes).
If all else fails, you could ask your boot seller and Risport itself whether they can be rebuilt stiffer. Most boots that aren't just one thin layer can be, for something like $60 or 70 a pair, plus shipping.

After I got Klingbeil dance boots, which were way too stiff for ME (I will always be a low level skater), and hurt from poor fit (I blame the fitter, not Klingbeil), I briefly tried barely used Risports. They were pretty low level boots, but were heat mold-able, so I did that, and did what else I needed to make them fit. I loved the way they felt, at first. But they broke down over 2 - 3 weeks, in maybe 25 - 50 skating hours. I went back to the over-stiff Klingbeils, which took almost a dozen years and a few thousand hours to break down. Could Risport boots be less durable than other brands?
