I have difficult-to-fit feet, wide but only at the front. The only off-the-shelf shoes I've found to fit me pretty well are the wide Lakes, with the top model being the best due to the heat-moldable heel. If I hadn't found these I probably would have gone the custom route with Riivos (he's semi-local to me, had him make some custom speedskates for me in the past).
That is my problem as well. I have normal size heels but very wide feet at the toes.
I found that Lakes fit OK, but I didn't like the BOA system on the 236s I had. I wish Lakes were easier to find.
I've been happy with my Riivos, other than the fact that I seem to crack the heel at least once a year. They can be repaired, but it's frustrating.
