Advice for Road Runners: The Ultraboost 21 from adidas is an excellent all rounder for everyday training. Dynamic BOOST foam cushioning delivers protection and amazing energy return for a mix of long runs and tempo paces. A plush underfoot feel makes your slow runs feel easier with high impact protection.
The rocker geometry aids the natural rolling of the foot, helping propel you forwards on slow recovery runs. An LEP (Linear Energy Push) structure in the outsole adds stability to the soft foam. This torsion system also creates a propulsive feel with snappy toe-offs for your faster runs.
92% of the upper is made using recycled ocean plastic. The Primeknit+ fabric gives an ultra comfortable, sock-like fit. With Forged Fit zonal support, it will feel secure while allowing the fabric to mould to your food shape. Finally, the durable outsole is made with 360 degree Stretchweb Continental rubber, for great traction on the roads.
Ultimately the Ultraboost 21 is a true all round shoe, that is perfect if you’re looking for one shoe that can do it all. With high cushioning for longer runs and enough responsiveness for your weekly interval or tempo sessions, it ticks all the boxes.
Shoe size is a personal preference and everyone's feet are different, but we want to ensure you avoid any pain or discomfort from bruised toenails, rubbing, blistering or pins and needles. Your running shoes should have enough width to allow you to spread your toes and should have some space at the front (we recommend having a half to one thumb's width of space from the end of your longest toe to the front of your running shoes). This usually means that your running shoe will be at least a half size bigger than your regular shoe size though this can vary from brand to brand.
