I wore a TRIKS running skirt in the Boston Marathon and have never been so comfortable in a race in my entire life. I had a number of women approach me along the course to ask questions about it (is it comfy, chafe problems...ect) and I really can't say enough good things about this line of cute, comfortable running apparel. This is a relatively new company that is offering us girls a GREAT product and I would like to see them do well. If you are curious about any aspect of the skirts, by all means please feel free to ask and I will give you my opinion/experience. I would highly recommend these for runners of all distances! Specifically, my experience is with Nicole DeBoom's line- Skirt Sports (or TRIKS). Get yourself one... you won't regret it!
