I have a load of these avail if any good to you, pm me if interested, mine are brand new in the stores bags and the label says it fits the ski march boot. I only have size Xl which is 13/14,It has a very thick rubber rand that is removable but very stiff,I've tried getting them onto a pair of issue assault boots size 12 and I just haven't got the knack,they are a heavy duty copy of a yeti. But the label states 'ski march boot'.
hope this helps.
