Have them, love them! Really like the SC3S treads and the boots look pretty smart too. Thinking I should invest in a second spare pair of boots incase they suddenly stop making them- would be just my luck!
I have them along with a pair of long ones and love them both. Getting used to the tread was a bit tricky at first but not only have they helped my feet sliding, they have helped my lower leg position too.
Hard wearing and comfortable which is a plus for someone with non-conventional sized feet and calves!
