Size 16 referee shoes
 

Does anyone here know a good place to buy referee shoes in US size 16 that also ships to Europe (the Netherlands)? Really hard to find anything around here :( (yes I have big feet I guess).

Here's a Solution
 

I wear size 8 and have two pair I no longer use. I can send them to you and you can duct tape the two rights and two lefts together to make size 16 each. :D

Sorry but every officiating vendor I looked at only carried shoes up to a 15.

You may have to go with a more traditional basketball sneaker.

I've looked at those too, but the only shop I could find that sells all black basketball shoes size 16 was the Nike store, which is quite pricy to say the least, so I was hoping for some alternatives.

Here, more and more associations are throwing the "all black" policy out the window. In my state, we're now allowed to wear shoes with up to 35% white on them. That might be your best chance. Find a shoe with a little white and see if the powers that be will grant you an exception. If not, there's always black paint markers.
