Glad to see you like them. They have quite a bit to tinker with despite the seemingly lack of straps. You may want to try doing the knee strap across the knee instead of down to the calf. That may help, as well, a tighter boot strap on these will help too.
I went the opposite route. Knee strap down to calf (just enough so all the velcro touches and that's it), calf wrap to second stitch line, boot strap as loose at it will go and I removed the calf wrap from the calf landing area. Made the pad feel more free on my leg.
I found the same issue for the blocker as well, just loosen up the velcro tab for the index finger a bit and you'll notice a large difference. Padding still sits on the paddle and protects your finger, but allows it to move when you need it to and feels less constricting.
Knee block won't soften up really. It's going to be like that for at least a while (i've been in my pads for 6 months now)
