"I ordered these online in my usual size of 6.5. I like the look and feel but I must return them because they feel at least a half size too big. I also bought the Rocket Dog Wheelie flat in 6.5 and it's slightly loose but fits well enough that I could keep them. I may try these in a 6 since I like everything else about them. My comfort rating is based on trying them on, not walking a lot in them."
