Ālpinestars SMX4+ (I think), goretex lined and they are fantastic. I have owned them since 2007 and covered over 40K miles in them. They have kept my feet dry on many monsoon rides, including last year's AR. They are the nuts IMO. The current incarnation of the boot can be seen
here and are Ģ170, which is what I paid IIRC, 5 years ago!
