Have been looking for a light-weight walking shoe that is provides both comfort and durability and finally found a match in the Merrell Siren Sport 2! LOVE these shoes! An added bonus-the REI store I purchased them from had them on sale! I trust the Merrell brand-having had other Merrell hiking boots. But the light weight of these shoes is just what I was looking for in a comfortable walking shoe. I usually wear a size 8 in women's shoe but was advised to go up to a 9 for the Siren Sport. They fit and look great!
