If you really want to look like a real russian soldier than get a pair of running shoes
Regular troops get black leather boots which are around 16-18'' tall, trust me, you don't really want to wear those things
Russians don't have anything like issue combat boots, from what I remember it's "go buy/wear whatever you like" when it comes to any combat units. Sometimes they even have sponsors buy high end western gear for special ops units. I'll ask a friend of mine what him and other people he was with used to wear during their trips to Kavkaz. I'll let you know.
Take a look at those links, especially at "voentorg" site which is biggest army surplus network in Russia. As you can see they don't sell russian made boots at all, mostly american stuff.
