I bought these shoes on recommendation of Chris Costa's company Costa Ludus.  I have been wearing these for almost 3 months now and I can't say enough about them.

Previously I had been a full size boot or cheap tennis shoes guy.  But I have worn my boots only a handful of times since I have started with these shoes.

The shoes are waterproof.  This is the biggest thing for me, I hate having wet feet ,which is why I used to stick with boots when doing anything outside, but these shoes have proven that they are water proof with out a doubt.  In the past couple of months, I have sprayed them with a faucet while filling water jugs, walked though puddles that covered the toe of the shoe. ran muddy trails/grass.  Any other tennis shoe that I have had previously would have left my socks soaked in all of these situations but these kept my feet completely dry.

They clean off really well.  I hate looking like a mess but I also hate having to put a ton of effort into keeping stuff like my shoes looking good.  I'm not sure what the upper material is but it stays clean really well.  Since I have started wearing these shoes I have helped a friend clean out her horse stall, ran around in the dust and mud etc.  So far they come clean pretty easily, A quick brush from my hand usually takes care of it.

SO em to be holding up pretty well.  The lower sides is almost like bedliner, just a little bit smoother.  it seems to be holding up pretty well.

They seem pretty lightweight, but I am comparing them to cheap retail store shoes and 8 inch steel toe insulated w/ goretex boots so my perception may be off.

Over all these seem like a really well made shoe that suit my needs really well
