Uses: Mainly for going outside with my son and trying to find ways to help burn some energy. This involves a variety of conditions, from mall walking to playgrounds to fountains. I wear size 9.5, so I ordered size 43. I intend on using this as an everyday casual shoe that can handle any environment and as an alternative to uncomfortable hiking boots.

Pros: Perfect fit, with or without socks. No break-in period required. Not too tight or too lose with plenty of toe room (and Im usually sensitive to lack of toe space). No ankle pain like I feel in some shoes, partly because they're low-tops but also because the inner materials is very soft. The lace system is easy to use and doesnt get untied like conventional laces. Truly waterproof; my socks and feet were perfectly dry, but my jeans were soaked in a fountain area. Very stable footing with great arch support; no problems with ankle rolling or instability despite the low-top design. The back is rounded which does make driving very comfortable. They also look like they're from the future.

Cons: Just some minor complaints that weren't enough to knock down a star. Without socks, the top of the tongue does feel a bit rough on the skin. The BIOM design does take some getting used to because the heel feels lower than the rest of the foot. This forces you to change your gait just a little, which I think is intended. Gets a bit warm, but my feet stay dry, possibly due to the magic of the Gore-Tex Surround. Also they cost some $$$...but I don't think you should be looking at ECCO if you want cheap shoes!

Other thoughts: I've only worn this shoe for a few days of real world testing, so I will make updates if anything changes! I don't anticipate making any thought because this seems like a pretty sturdy pair of shoes.
