I wasn't able to go to the store either.
What happens is they send you a foam mould with instructions on how to use it (not hard!) then papers for tracings of your feet and measurements. You will need to provide height, weight, jump, and level information. It was really a pretty simple process, and I just called them when filling out the options sheet and they walked me through what everything was and what they would reccommend for my feet.
I was lucky as my coach was trained to fit them, but really it was quite simple! then it is 4 weeks to make.
I don't think they do heat moulding, they may, but mine are full customs and I highly reccommend that! Go like their facebook as well as they sometimes run sales, I got around $100 off!
