I understand why you want to convert your Doc's.. like Riverkilt mentioned in another post... I have big,wide feet and I cannot just buy shoes without trying them on first.. what one calls wide, may not be wide enough... I wish you luck on your search... and if you can find some Ghillies that fit at an affordable price...good deal... I hope you are able to get what you need... be it a reasonable conversion, or a new pair..
