Yesterday I got this pair of road racing shoes.
It's the Torin 5 by Altra. They are the lightest running shoe I've ever owned. They are LIGHT LIGHT LIGHT! Granted, I've only worn them once (yesterday) but trust me when I say that they feel twice as light as my old pair of New Balance 1080s. I frankly cannot believe how comfortable these running shoes are. I will put them through the paces as soon as I've fully recovered from Saturday's ultra. I expect the new EgoMax foam to provide more cushion than my previous shoes. I picked up my pair from our local running shoe store in Wake Forest -- Run-N-Tri Outfitters. My thanks to Bryan Staffey and his peeps for great service and even a discount. Bryan himself has decades of experience in the world of competitive running and has trained his staff in fitting techniques and bioomechanics of the running foot. They will listen to your problems and help you make a sound decision.
I hope you will consider trying on a pair of Torin 5s when you're in a shoe store. Maybe they will work for you.
