I am new to soccer at the age of 14 and was wondering what would be the best shoes for an indoor league and a normal league on a grass field. Also I wear a 13 size shoe, is it true that I should get 2 sizes smaller? Any comments are appreciated. Thank you!

mate, try on whats comfy, some peeps say that you should get such and such boot, just try it on in the shop, ask to do a few keep ups, see how it feels choose from there

Comfort is definatly the most important factor.

what shape is your foot (arch, no arch, flat, high arch)

i'd say look at nike, adidas, puma...they never dissapoint

comfort wise i would go with LEGENDS total 90 or preds
if not u can always wait for some otha ones to come out
i change my mind: 7406 or legends (ronaldinho 1's look nice)

i would say just get any cheap boots just in case you're not too keen on football. i don't find it smart to get shoes that cost 100+ and then realize you don't want to continue

ya u don't have to spend all that money on ur first pair of soccer boots or cleats. same thing. i know all these kids talk about vapor this and predatopr that, but most of us have been playing for a while, and like it. so buying a pair of high end boots is really more of an investment than anything else. id reccoment getting something moderatly priced, $40-$80. the MOST. make sure u try on everything and get what fits ur foot right. don't worry about cool colors or brands just yet. the only online shopping u should do is to save money i would say, after u try on a pair and find whats right for u. u want a shoe thats comfy, DUH, but tahts not too long or short. it should be just right. and be careful with the width of the boot. some are made for narrow feet while others are made on a wider last.

Yeah since you've just started out on soccer you dont need expensive cleats yet, like what Bazo 14 and Romeo371M said.
Perhaps you can get cheaper versions of boots like the Pred Pulsion instead of Pred Pulse, f30 instead of f50+, Mecurial talarias instead of Mecurial vapors (only get these if you have narrow feet), nike mystics instead of legends etc.
Only if you are really into soccer and play it like 3 times a week then you get the better cleats.
