Did you have a pair of these?

view from the past

I bought mine when they first came out …. A significant improvement over the old style boot foots!  They couldn’t take a lot of abuse but at $49.95 you could buy a new pair every year or so.  I always traveled with two pair in case I got a puncture.  Today’s Gore-Tex and comparable products are a great step forward in performance and durability, but not in price!
