These shoes become terribly uncomfortable for me after about 40 or so miles. However, the shoes are quite nice and may not have the same results for others. I bought these because I have another really great pair of LG shoes that I really like. The main issue with these for me is that my toes start feeling like they are on fire once they begin to feel uncomfortable. They are not too small. They are actually about one size too big. I've tried different tension with the boa tensioner with the same results. I am quite baffled as to why I get these results because they seem like very nice shoes.
