Welcome to the forum!
I've got a pair of 1.4's, White and Orange(Lava). They're very comfy, but please note that they are half spikes, only on the front, with the plastic studs for want of a better word on the heel. I use them for batting as the half spike helps with forward movement but makes changing direction (Fielding) a little more tricky. I use a pair of full spikes for fielding.
Size wise, they are fine for length, if you're a 9, get a 9. However, you may find that they are a little narrow due to the speedframe technology. If you've got fat feet you may struggle!
