Just arriving this week is the Asics Nimbus and Cumulus! The Nimbus is basically the same, just a few new awesome colors and updated Guidance Trusstic System to help with a more effecient/fluid take off. The Cumulus on the other hand, has reaped the benefits of the FLUID RIDE cushioning system. This softer, more efficient cushioning has already had rave reviews from customers and an excellant update to an already awesome shoe! Come try them out!
