These are the latest creation by Nike and possibly the most comfortable trainer I have ever worn! They are the Missoni for trainers, a knitted sock effectively stuck onto a sole that is cut into squares and means the sole is so bendy you can bend them in half! They will give your feet full flexibility. These trainers are ideal for long runs, they build up the with walking in them and they strengthen the foot e core part of the leg which means that knees and legs are then taken care of. Don't though wear them in the gym as I did very little support on the ankle. I have been given them on Friday the day of launch and haven't taken them off, socks with soles, I may never take them off they are comfortable and look cool, job done!
