I have 2 pairs of these (Five Ten Impact Pro Mid Flat Pedal Shoe). Some are short, for summer, the second are tall, for winter (in Estonia, usually from 0 to -20 degrees Celsius). I would call these shoes shoes for ballerinas. It just looks wide. Here are Keen shoes, these are actually shoes for wide feet. Five Ten Impact Pro Mid, I have 10.5 US, or 10 UK. My foot size is 43 EU ( length 27 cm and width 11 cm). In summer, on a thin sock, 2 - 3 hours is normal, then the foot gets tired...
