Strengths: Superlightweight, super breathable, incredibly cushioned and comfortable for something so light. Every bit as cushioned as the lunaracer, but with much better support for over-pronators. The light, breathable material at the front keeps feet cool even in summer, and the heel cushioning especially is extremely comfortable.
Weaknesses: Mesh at front easy to poke holes in with toes over time, no big toe protection. Very narrow.
Overall: Made as a lightweight racer I use them for most training, because the cushioning is suitable for longer distances. An improvement on past editions and every bit as good as more recent ones. Look great too.
Strengths: Fits very comfortably and snugly, with almost no stitching inside the forefoot to rub, and the most cushioned ride I've experienced. Despite the runnersworld review I felt it was still quite flexible in the forefoot, and very sturdy, although it's not the ideal shoe for intervals or anyone looking to increase speed rather than distance - the Calis are far too comfortable for that! However, the price is very reasonable for a great pair of shoes.
Weaknesses: Almost too comfortable, if that's possible.
Overall: I love them, when they wear out I will definitely be getting another pair.
'Comfortable, reliable and sturdy distance trainer'
Strengths: Structure is quite subtle Very well cushioned forefoot Comfortable fit Looks nice
Weaknesses: Chunky, a little heavy Not very responsive compared to others in the class
Overall: A good distance shoe, great for regular training but for speedwork or anything shorter than 10k a lighter shoe would definitely be far more responsive and suitable. Clunky for short distance, great cushioning and reliability for >10k.
