So far I'm liking these shoes. Been using it at the gym for a while and at work. Bought them coz of their water proof properties and so far its holding up when I'm on my site inspections in the mountains. I sometimes walk on trails or on muddy conditions while on work but these shoes surprisingly keeps up with the the pace im in, though they're pretty slippery on wet tiles, so better bare that in mind. Sizing is a bit off. Read on other reviews that these spine venoms are a half size larger than the industry standards. I can safely confirm those claims and say they are a bit larger. I usually but a size 11. 5 but contented to wear size 11. A big con for me though, the shoe is a bit narrow. People with wide feet please take not.
