I have big feet and wear booties. On my 2010 isonic 101, I had to replace the drake straps and also use the additional inserts to widen the straps further.
Also, to place the straps a bit inboard, I mounted the straps using the offset holes in the straps rather than the center one. The serrated metal anti-twist plate still fitted okay. It's a small change, but I think it helped to make the straps easier to get in/out of.
