Sorel Women's Running Shoe Size 9 US (40 Euro)

Just got these shoes a week ago while visiting Montreal. I was in a rush and settled for a half-size too small (9 instead of 9.5) and I shouldn't have! After wearing for two days I realized this half size smaller is just not OK for me in this shoe. So these shoes which I paid 155 CA$ for and wore for 2 days can be yours for only 50$. I think the sizing is probably spot-on. I knew better, but was hurried and bought them anyway.
