I regret not having returned two pairs of Charles Tyrwhitt shoes I purchased earlier (albeit at $85 a pair), but now that I have them, I wear them occasionally in any case. But I find that they are very rigid, much more so than what I am used to (mostly Italian, softer leather). Is there anyway I can soften the calf leather of the CT shoes? Hurting longevity is not an issues since I don't intend to wear them a long time -- I just want them to be more comfortable, especially around the ankle bone. Appreciate any advice.
