If you are used to wearing just basketball shorts and sweat pants, skinny jeans will probably be pretty uncomfortable to you. If you have to get skinny jeans, I recommend getting jeggings. Jeggings are a cross between leggings and skinny jeans, so they still have the skinny jean look but they'll probably be more comfortable to you. I recommend buying them form Aeropostale. I bought a pair from there and I LOVE them. (:
It really depends on how tight and stretchy they are. Try them on before you buy them though just to make sure and if you can walk in them easily you should easily be able to kick a ball and stuff. But most skinny jeans are stretchy so I wouldn't worry about it :)
Well it really depends. its not like your going to wear a pair of skinny jeans that you literally cant move in anyway but if your are able to walk in them id say it will be okay. Unless you were planning on doing the splits ;]
Depending on how tight they are, you may crush a ball when you attempt to kick a ball. Ouch.
