This is actually something I need, however the last would need to be perfect. I have the C&J RL dark brown cordovan McCallum which I think is the 325 last and while it's a fantastic chukka, the fit was always slightly loose which has resulted in mucho ripples (could have used a 12.5D but this size was not available). Because it's a plain toe, chukkas in cordovan need to be a perfect fit I feel.
I see what do you think of the plain toe boot? For example Galway 1 that somebody posted while ago. It is a pity that C&J offer only four cordovan colors.
