Do these have any value anymore?

They just say "boots" but are a super dark blue color, nearly black with all you can see being a little blue sheen near the toe. They dropped off of Leprechauns (along with the rest of the outfit) a long time ago and even about 6-7 years ago it wasn't unusual to get 700k-1 mil for a pair on Atlantic.

Most people didn't have any idea they were special, so you had to find a knowledgeable buyer though.

How about these days?

As usual it varies from shard to shard. I know I have several complete sets tucked away. For the day I can get a keep/castle and set up a rares collection. If I had to just guess, if it is just boots, you need to find a leather dye tub and if you can dye some leather to the exact color...well the price is going to be near nil. But if it is still a color that can not be duplicated, it might have retained most of its value.

They are still very valuable, the most valuable part of the set. I suggest going to the Stratics Rares forum, as there was a discussion on these within the past couple days. Value is based on shard and authenticity, but they are still very much prized.
