My advice is for Men & Women alike because I'm pretty sure SPD's are like all pedals unisex.
Buy Cheap find an e bay bargin on shimano spd's new your looking at £20. not everybody takes to spd pedals.
Be aware that most spd shoes are NOT WATERPROOF & overshoes are not that effective either use seal skin socks to keep your feet dry.
in the real world of riding trails I'm getting off & getting back on my bike to open Bridalway gates. (which sadist puts them on hills) i find hill starts 100 times easier with a flat pedal.
In fact i find I'm dryer & more comfortable with a lightweight walking shoe & a flat pedal, this combo has sorted me for many hundreds of miles.
