Everyone's preferred efficient manner to move in your toon or tube. These fit nicely over my Korkers Guide 11 boots but my high forefoot makes other fin options more comfortable. Worn twice. You know what they cost. What is your offer? Don't rake me over the coals here, but a truly fair offer will have these added to your toolshed fast. Would consider trade for something of similar value. If you have ideas of things you don't use that you'd be willing to move let me know. I'm not really looking for anything specific, I've just begun my gear collection process. Thanks.
