Sounds normal. I ordered mid-Jan. Followed up early Mar and they arrived within a few days.
Just send them a message in a week or so. They're very efficient.
I just built my own set-up for AU$16 with purchases from eBay. Two 5v brushless fans running off 4xAAs each. The AA packs have their own On/Off switch and Velcro easily in place.
Hi! I just received a pair of US10. It's equivalent to our Australian/UK 9. The fit is good. Plenty of room in the toe but, as expressed by TK Boots, they are narrow. I have absolutely no doubt they will stretch. A great boot and impressive quality.
