Weaknesses: heel is very narrow with no give leading to an achilles problem for me.
Overall: Prefer 2110, much more comfortable the heel area is a little hard and has caused me some achilles pain, used to love this series and have gone back to 2110m which for me are far better.
Overall: this is my favorite trainer, I run about 30mpw and the support and comfort on this shoe is first class. A bit pricey but well worth it. No blisters, chaffing and plenty of room for wide feet.
