Had my shoes bought on carpeting because of the low price for indoor tennis and up now supported in the hall for hours. K-Swiss generally fall 1/2 size smaller, so the size 11 1/2 instead ordered size 11. The shoe fit perfectly, not suppressed, conveniently from the beginning. Very good finish and cushioning The sole gives good grip on carpet. Important: The sole is rounded at the outer edge, so it makes it easier to bend the foot with a greater step. Compared to running shoes, the shoes, especially the soles of relatively strong material that stabilize the foot well are .. Therefore, it is also more difficult than, say, a normal jogging shoe. By comparison, the K-Swiss shoe weighs 464g (single shoe), a generally softer running shoe has only 370g. For me personally not a big disadvantage, but that's why a deduction of points.
