I just bought a pair of Nike Frees and i'm wondering if its okay if i walk in it... I've been injured and i've been resting for 3 to 4 weeks now... and i just want to know if i could just walk as in walking in the hall way to class (i'm a freshman in high school by the way) and such. It wouldn't make it worst would it? Because i'm not running and putting so much pressures on my knees...
