This shoe is very light, with a very thin sole (something that I'm not so sure is a positive feature). Appears durable, I have worn it in the summer and early fall seasons only. With a significant part of the shoe being covered in mesh for ventilation, this shoe is not very good for colder or rainy conditions. Sizing was an issue. I buy most shoes (especially sports shoes) at least 1/2 size bigger because of the fact that during rigorous exercising feet slightly expand. Well this model fells very tight on my foot prior to  exercising.  After running feels even tighter. Also feels tight in the upper area around the shoe laces.  I would not buy this or similar product from this company in the future for the above reasons.
