These shoes are exactly what I thought they would be, EXTREMELY LIGHT!. However the downfall with these shoes are their durability.  I bought these to test out to see if they would stand the test of triathlon, as of now i don't think they will (for me anyway)  The shoe offeres little to no support and the tread on the bottom has worn out quickly just by walking in them.  Although I will not wear these for triathlon I do love walking around in them and used them everyday.
