Strengths: Very light and very comfortable. I'm used to wearing Wave Riders, and still wear them as my second pair of trainers. I was originally very weary of going for these as I'm not biomechanically perfect and I wear orthotics, but the guy at the Mizuno stand (it was at the Berlin Marathon Expo) said that since I have the orthotics, I don't need extra cushioning. I went along with his suggestion and haven't regretted it. I use them as general trainers, on long runs, tempo runs, speedwork - these shoes are perfect for everything!
Overall: Great value for money. Quality shoes that are durable yet light and very comfortable. These shoes are perfect general trainers for the lighter runner or can be used by heavier runners as speedwork / racing shoes.
