Prices of Planika boots...
http://www.vsezasport.si/sporti-na-prostem/pohodnistvo/pohodna-obutev/ it seems to me that the prices are the same everywhere if there are no special deals
As for Alpina CROMO, I can tell about the low CROMO LOW, I use them as everyday shoes (work and private), I'm very satisfied, but for various hikes or hills they don't suit me because they have too much space for toes in the front part, consequently toes move too much and rub (blisters).
best regards
