I was Kayano runner for years then I felt recent models were too heavy and pricy. I stopped by my local running store, and I was told about DS trainer. Never paid attention to DS series I was skeptical, and instead picked up 21XX model at the time. I still felt 21XX was missing the point, and I remeber the advise from the store. Why not shelling out another $70 (ouch). I picked up the DS Trainer 16.5, which is the red model. Apprently the production change happened and 16 (the pinkish white model) and 16.5 are slightly different on fitting. WEll, I must say I am very happy with my choice. They are super light, yet still provide enough support that I need...and 1/2 the price of Kayano! Wow.

Of course these are light weight shoes, hence I don't expect to take same level of abuse like Kayano. But I'm really liking them so far. Oh, and I used to wear wide Kayano, but with DS trainer I wear normal size.
