I have a grand-daughter who runs with ASICS and won't trade them for anything. I have worn ASIACS running shoes for years and in my mind they are absolutely the most comfortable, durable and affordable shoe money can buy.
This video review looks at the ASICS Gel Kayano 23 and it is a very honest review with a conclusion that is not usually found in reviews of this type.
The reviewer gives the Kayano 23 high marks for it's construction and comfort. However, he contends that while the 23 is a great shoe it is not worth the price differential found in the Kayano 22.
I checked some pricing and found the Kayano 23 to be about $30 more and this reviewer says that there is not that much diffence to merit the price.
A great video that still extols the virtue of ASIC running shoes but is unbiased in there assessment of the new model.
Purchase ASICS when you make your next trip to the shoe outlet and buy some Kayano 22's if they have them!
