I just switched to the 1130 from the 2130. I'm very happy, except for a seam that rubs my little toe so badly the front of the shoe was completely red after a 65 minute run. I had a band-aid on that toe, too, b/c I felt the seam yesterday (my first run in the shoes). I really like the shoes except for this problem, so I'm wondering what suggestions I can get to relieve the bleeding. Thicker socks works, but I like my cheap white socks... any other ideas?
Also, what's the deal with the Asics I.G.S.? The 1130 doesn't have it and the 2130 does, and where I felt like I was fighting the 2130 to pronate normally, the 1130 seems to allow me a more natural footstrike. I'm thinking this might be the I.G.S., but I'm not sure... does anyone know more about this?
