Yes indeed. One of my customers was trolling the internet and discovered some blue tailcap boots! Not GITD but a pretty darn close match to the fluorosilicone. Bad news is they are expensive...for tailcap boots. The good news is that I bought out every one they had...so I'm not sure any more will ever be available.
These will now be an option during checkout and, for any existing Alpha owner, I'll send you a boot at my cost + shipping in a first class envelope = $2.50
Just send paypal to email@example.com and note something like "blue boot!" in the comments during checkout.
