No substitute for properly fitted boots. It is hard when a lot of stores only carry a 'standard' width, and why buying boots through the mail is very difficult. When I sold boots (hiking, climbing, etc.) we would sometimes find fit differences between 2, 'identical' pairs. We could also stretch and condition leather boots to some extent. But steel and composite toes are less forgiving. I think that they are very important, and you may be finding a width problem if your toes get jammed up against them.
I do have a pair of Husqvarna / Viking rubber boots with chainsaw protection, similar to chaps, embedded in the instep and sides. These fit somewhat loose, like most rubber boots, and are also the least expensive chainsaw protective boots available. Good for cutting in snow and wet conditions on mostly level ground, but not for a lot of climbing over logs, etc.

Several places sell non-chainsaw rated 'trimmer chaps' which be lighter, and may not absorb water like leather would. Just remember, that they are not chainsaw rated!
