I whole heartedly agree with this! Suede is 100 times more comfortable! Now that it's summer, I finally decided to try to break in my black calfskin chypres. O.M.G. these are like medieval torture shoes. It has been a week and they are still so stiff and rub against my pinky toes, and after the first day, the top of my foot was super sore and I don't even know why! I started by wearing them with socks in the house, then without socks, and even tried the hair dryer trick to soften them and it's only helped marginally. Then I remembered I have several other pairs of chypres, so slipped on my suede rose porcelaine pair... it was like slippers from heaven compared to the black calfskin! The rose porcelaine ones are also half a size smaller than my other ones (it was the only size available in the store) so I wonder if I actually needed to size down because chypres are wide on my feet. So to experiment, I tried my rose escarlat pair which are also suede but half a size bigger, which is actually my normal shoe size. They are also very comfortable but I do feel like my feet slip around a tiny bit and find myself doing the toe grip. So I know some people say size up, some say they are TTS, and now I'm wondering if I needed to size down! I guess point of the story is suede is infinitely more comfortable, and one really should try on a couple different sizes to see which is the best fit.
p.s. I have epsom chypres as well and they are also more comfortable than the black calfskin. And for some reason the studded calfskin even feels more comfortable than the plain black calfskin, which doesn't make sense. I might just give up on those!!
