I have a borrowed pair of xc skiis that I tried last winter that were sized taller than me when holding vertical (I'm 5'5") that seemed to work ok on fit (the GF that loaned them is about 5'3" to 4"?)??? Only had a chance to use them once. I have just a basic pair/set of gear I was going to buy for myself at a local sporting goods store, and the sales guy said that about "head height" is the general gauage for fit. Or slightly longer. Whatever these skiis are, I am inbetween a small and medium he said. I want to go back and get them before sold out, but what size do I really get? The slightly shorter pair, or longer? I don't want to waste my $ on the wrong size, but don't want to feel like I have "too much" skii to manipulate either. Just a new xc skiier. Think the style would be considered "skate style". Groomed trails, no backwoods skiing, for xTraining purposes. Thanks!
