Apologies if this has been asked before, couldnt find anything when i searched. I am after some Lowa combat boots but cant get to a stockist to try a pair on for size. I take a size 10 issue boot, but i tend to use sorbathane insoles which will effect the sizing i need. Are lowas close fitting, and do they have require an additional insole? I was hoping someone here may have similar sized trotters.
