If you wear thick socks for hiking in the winter I?d consider going up a half size or a whole size. My husband is 6 feet and he wears them sometimes and his feet is bigger than mine and they fit him perfectly. Not hard to platinum. Now i have to keep it plugged in just to listen to it. They are snug so you can move all you want and they wont fall off. But IMHO, daytime use shows it on the weak side. Standard shaped wine bottles only because of the void in the middle BUT, it can adapted. I just learned of these Treblab speakers last week, and how they connect with either Bluetooth or a patch cord. This game is fabulous, if your worried your child isnt getting enough exercise then a must buy. Nice pair of footwear.
