I have worn this Chaco style in all conditions for many years. The cloud feature is a little softer and can come in handy early in the season while your legs are getting stronger. Not really worth the extra cost and it's not known if this extra layer reduces durability due to the increased risk of delamination. I really like the design of their soles. I don't know why but they seem to have more grip and slightly better stability on uneven surfaces. In general, as always, very happy with Chaco.
