Taking this to a two day hiking trip and hoping it lasts me the whole time. Maybe I could have tried one size bigger, but the length was already perfect. I bought these for my wife for Christmas. Im 54, 185. TLDR; stick to your regular shoe size. But after that hassel its a cool table. often walking quite a bit of the day. great headphones. 25") or smaller tires. It?s completely sturdy.
