I have discovered the joy of wearing ballet flats. I’m a guy and I tried flats for the first time about 8 years ago, but in the interim more flats have been made that fit me (size 10 mens = 11.5-12 womens). I live where it’s hot and sandals aren’t all that practical all the time but flats provide foot coverage and a very comfortable environment. Easy to slip on and off and look great. Sadly, men haven’t adopted them, but I did talk to the people at Corso Como and they make the larger sizes in their flats knowing that some of them are sold to guys.
I have also had success at Barefoot Tess, DSW, eBay, Amazon and a couple other vendors. I now have about 25 pairs and wear them out about at least once a week…. sometimes more. Hardly anyone ever notices, but when they do it’s 95% positive. I dress like a guy in all other respects but have found I love wearing flats.
