@iUnknown, I have barely any space in front of the big toe, certainly not a thumb's width. Probably the boot is too small rather than not... I'll check at Iglu Sport, thanks.
Otherwise I've had ankle problems for many years (tons of sprains on both) and for any even short not too flat hike I prefer high boots.
@ribic, thanks for info, I checked Intersport at BTC, but there were none. I bought them right there about 4 years ago, got them for 50EUR on sale, best buy of all time. Definitely I'll check Austria too, I've been there a lot lately.
Do you have any brand tips? I have quite wide feet (those bone outgrowths - "sixth toes" on both feet) and quite low instep? And apparently very sensitive toenails (I've "replaced" them about five times in the past, not related to mountains)...
Thanks again everyone, no one lacks prompt help and knowledge
