I have been searching for another pair of ZigTech Sonics. That was the most comfortable shoe ever! I put them on and felt like I was walking on foam. They were so worn out I am searching for another pair or similar. After returning another Zig product I asked the experts from Reebok what would be best. They recommended the Zigkick Trail. I love the colors. I run trails every day. I don't think the top of the shoe is going to hold out like the others that had more support. I always wear a 6. I run at least 5 miles a day in up and down trails. I noticed they lean a little forward, so going up hill is great. But going down they push my feet forward and gave me blisters. Not good. I have tried different socks to see if that makes a difference. I am off to the mall to try to find other Zig shoes to see any difference. If they didn't shift me forward they would be great. Not sure if I need to return them. But would really like another pair of Sonics. I love Reebok shoes and their removable foot bed. They provide a lot of cushion!
