First, I'd just like to say I don't recommend you buy them, but I'll give you my experience with them since I wore 1 pair exclusively before improving my steez. It was the only pair of shoes I had for that period of time, so I wore them everyday. I thought they were quite comfortable until the 2 year mark. After the 2 years of wear, they became extremely uncomfortable, and I had to get another pair of shoes. The insole is really thin, providing little arch support. I replaced mine with another insole, but they were still uncomfortable, so I can't use them as beaters anymore. The last time I wore them (~6 months ago), I had to walk pretty slow or experience great discomfort in my arches. They fit short and narrow. I'm a 7.5D, and I wore mine in a 10. To put this in perspective, I wear 40 in common projects, but the CPs are barely shorter than the cesario lo I have. Truth be told, I should've picked a size 9.5 for a shorter length, but I felt the width was too narrow. You should size up by at least 1.
