I like the color of the one you're standing on. It has a nice gloss! Which shade of gray is that?
Also, how do they feel with bare feet? Considering Swisstrax myself.
Thats pearl grey and I like that as well, the lighter colors I assume will show more dirt, but I also do not want all the light darker colors to make the room look drab. We are kicking around the idea of some accent colors but hell I don't know.
The one thing I do know if I hate it its not like epoxy where I have to just grit my teeth and deal with it.
As for the bare feet its a non issue can you feel it yeah but its not uncomfortable. If you want something flat they also make a tile called smoothtrax that is gen two of this tile. Only issue I see with it is there is more surface area to get dirty and the gaps in the tiles are less so not sure if dirt will tend to sit more on top.
