The Pro boots that were issued 95 ish, are excellent,
I stopped wearing flying boots and found that in NI the boots kept my feet dry and in Norway the boots plus a pair of thick socks were all I needed,
If you use foot talc to keep your feet dry in Hot weather they can be used all the year round.
My pair have given up after 7 years of use and I am now trying Matterhorns,
But I can strongly reccomend Pro boots.
