You may want to look into a pair of good racers.
One I would recommend is the Adidas Hagio, which is supposedly unisex.
Meanwhile, if you are already an experienced runner and want to try something called 'barefoot running', then you may consider this New Balance Minimus MR00.
The MR00 makes use of a Vibram outsole, creator of the 'Fivefingers' shoe. The MR00 claims to have zero drop, which means that the heel is parallel to the forefoot unlike in conventional shoes, and this claims to reduce injuries.
