Does anyone have any other suggestions about a pair of lightweight trainers with a medial post, similar to the DS-Trainer? I have been wearing the DS-Trainer for the last 10 years or so and love it, and want to continue wearing it but want a complementary shoe. I've been using the Kayano for just as long but honestly at 145lbs and with the way the shoe has been going it is getting to bulky. Thanks for the advice!
