and, ill say it now and I'll repeat it in the forum
Read, Research and Understand before you buy anything. There is a lot of JUNK out there being hakwed with the 501st approved label. Dont believe any of it. There is very little that is commercially produced and marketed on dot.bomb websites that meets our approval. I have a list of Squadron Approved vendors that I maintain. Wampa Wear is one of the few sites that we know is top quality, reasonably priced and very quick shipping when hes in stock.
Your first stop for your 181st is your Jacbkboots. They top out around size 10 1/2, so above that we typically use round toe motorcyle boots.
I have an active list of boot sources here:

we have talented seamstresses in the Garrison that can help with Juno, so that should not be a problem at all.
Good to have you with us!
