LF Ultras. They last better than any other. just ordered my 2016s even though my 2015s are still like new after months of 3 times a seeking riding cable. I'll put my 15s on my kiteboard and ditch the clapped out Harley's that are on there now.
I found all LF boots to be a weird fit for me. They are either too big or too small, I'm right in-between their sizes unfortunately. Something to be aware of, try before you buy.
I have rode the vantages for 3 years now and haven't had and issues with them, they are simple to get on and off and if you want more flex out f them just leave the top velcro slightly looser.
