I REALLY wanted to love these. I have owned numerous Saucony's and these are for some reason not working. My feet are incredibly hot in them. I have not changed my socks that work in my other shoes....this particula shoe....My feet become so hot that I must take my shoes off to cool my feet down. I do many races and after my 3rd race within 2 months...I simply cannot run in these.  To include riding a bike. Super comfortable shoes....just too hot to enjoy.
