for the last 6 months or so i have been training in the nike air streak spectrum vapor 4s. Very light low profile. They used to be 60 bucks but they ran out of my size. Now i can\'t decide between ultimate 81s and limber up moscows. the pros and cons i am weighing is that the moscows look lighter but they also have a weird outsole, the wavy stuff. Has anyone ran mileage in these? How is the ride. Any help is thanked. I am used to training in flats but i can\'t decide. Thanks
