Please note: This is an unisex shoe. Women purchasing this shoe should order a size and a half smaller than their normal running shoe size. For example, if your normal size is an 8 US, order a 6.5 US. The Superblast 2 is one of the most sought after super trainers on the market. It's known as the ultimate 'do it all' shoe featuring a speedy midsole setup and wide stable base. The second edition features an updated design with a woven engineered mesh for a stretcher, more comfortable fit. The midsole now combines bouncy FF Turbo Plus foam (the same as in Metaspeed Paris race shoe) with a bottom layer of FF Blast Plus Eco to deliver a soft and responsive ride. The new AHARPLUS outsole enhances durability for reliable performance over a demanding training block. This super trainer has been the go to shoe in the running community for long runs, but it's versatility covers you from easy runs all the way to your first marathon.
