These trainers are so light it's like wearing a pair of clouds on your feet. This is the second pair I have bought as I was so impressed by the first pair. I think the description of 'Fitness Walking Shoes' is a little misleading as the material they are made from is actually a mesh fabric with lots of tiny holes so they are most definitely not waterproof. They are however very comfortable to walk/run in on a dry day as the material allows air to pass in and out giving your feet a cooling breeze. There is no need to use the laces as the elasticated material provides enough grip to prevent them from slipping on your feet whilst walking or running so I have removed the laces on both pairs.
