Is New Balance discontinuing the 730? It looks like Running Warehouse has limited sizes available. I hope not! I love this shoe! I'm a forefoot striker and love my Kinvara 3's, but seem to burn through them quickly. I only have 50 miles on my 730's, but they hardly show any wear. I only get about 200 miles out of Kinvaras. Also, any recommendations on shoes similar to fit, ride, and durability of 730's? Thanks in advance for any advice.
