It's very light, very comfortable for walking, but if you run over 3 miles get ready for blisters. At first I thought it was my new socks since I never get blister with any Asics shoes before, then kept switching socks and shoes found out it was this pair of shoes that gave me blister.  Very dissapointed with running shoes that can't use for running.  It's OK for 2-3 miles, but after 3 miles blister started.
