Research shows that women who wore high heels have shorter muscle fibers with thicker and stiffer Achilles’ tendons. In the long run, it limits the motion of ankle and heels-wearer will find it painful to walk in flat shoes. Occasional swabbing between lower heels and high heels keep your tendons stretched and prevent aching feet. Regular stretching relieves the tensed muscle fibers. It may not be good for you but you need not give up the killer heels once and for all. Choose your shoes wisely. Platform shoes are often better than stilettos, and always opt for shoes with a snug fit.
