"I own few pairs of Clarks, dress shoes only. This is the first flat Clarks I've bought. Sadly, I have to return them, because they are not only too wide but also too long. The shoes are comfortable, but run at least half-size longer and wider. I always purchase 6M for Clarks dress shoes, and they are not wide at all, I'd say rather tight. These shoes are not size 6 and they are not M. I tried similar style in the store in 5.5 M and 5.5 W - those are too short. This is how it is: 5.5 is short, 6 is way too long."
