Got a bit more gowing to be sure, but I'm guessing female.

Yes, toe pads are not very telling. Females are a lot bigger, plumper and have a more arched back than the males. Hard to tell until they are sexually mature though. I have a 'pair' ~ the same size as yours and I'm still not certain. My adults I can tell whos who from accross the room - real obvious.
