Crashing with straps doesn't worry me, I've had big crashes at 35+kts windsurfing and never hurt my feet/ankles
Just that windsurf boards don't have a big anchor beneath them that causes a ton of leverage.
I think board width is a bigger problem. My wing board at 20" wide will still roll fairly easily despite the foil. Previously windfoiling with an 85cm wide board was a bigger risk, particularly if hooked in.
