Changes

* '''Flexibility'''. The Takumi Sen is far less flexible than other shoes in its weight category. If you're looking for a light weight, but stiff soled shoe, then this may be a good option for you.

* '''Outsole'''. The outsole is covered by tiny protrusions that are covered with plastic that is the consistency of sandpaper. This provides a quite remarkable level of grip, and the outsole has the logo of Continental tires, so I assume they're responsible for this novel material. This is a high grip outsole for asphalt and similar surfaces; it is not for trails or dirt.

* '''Upper'''. The upper is remarkably thin and completely inflexible. It has good breathability, and its thinness means it dries quite quickly. The padding around the ankle opening is probably adequate, though not overly generous.

* '''Tongue'''. The tongue is very thin and unpadded.
