Skechers Flex Appeal 3.0- Insiders The Skechers Flex Appeal 3.0- Insiders is an athletic style shoe with soft responsive comfort to help your feet through those intense workouts. A soft woven heathered-finish jersey knit fabric upper and an Air Cooled Memory Foam insole to ensure the feet stay cool and dry. Jersey Knit Upper Soft heathered uppers will encase each foot in ventilated comfort. The breathable construction increases airflow to create a better, healthier environment for your feet to thrive in. A smooth synthetic overlay at the laces panel adds durability, plus the soft lining provides next-to-skin comfort. The (nearly) one-piece fabric upper produces an irritation-free fit, reducing the risk of rubbing and blisters; because we know how those can ruin your day. A heel tab makes for easy on-and-off. The padded collar and tongue offer custom support plus protection against lace pressure. Shock absorbing midsole An Air Cooled lightweight shock absorbing midsole has been added to the show in order to relieve your ankles from that pressure when you are training. The midsole works to actively and efficiently absorb shocks before they can reach the sole of the foot, this reduces potential injury and you strike down on unforgiving terrain. As well as preventing impacts from reaching the foot, the midsole transfers shock into rebounds, giving you an extra boost on every step whilst also providing support and cushioning. Additionally, an air-cooled memory foam cushion comfort insole provides ample underfoot cushioning that moulds to the shape of your foot and provides personalised comfort. Flexible Outsole The Flex Appeal 3.0 insiders provide adaptive traction that moves with your foot. Durable rubber adorns high-wear areas, resisting the traumas of heel-strike and toe-off to deliver you with a reliable and long-lasting neutral running buddy. It is extremely flexible, meaning there will be no lasting damage from excessive forces acting against it. The rubber itself is durable, which means that it will retain its shape and definition on rough terrain.
