Rolls easily, but structurally it?s still somewhat flimsy, so I push/pull from the center of the side bars. I bought them for my engagement photo shoot and am looking forward to wearing them with both a white dress and white pants. If you plan to use these with an iPad Pro or other device which has a USB-C port. Clearly I think the shoes are worth the purpose I purchased them for (throw on instead of a tied tennis shoe, walking on weekends and to/from work). Aun están a prueba, son cómodos para salir a caminar o hacer ejercicio. The problem is seller! The P4 isnt even 2 months old and most carriers are practically giving them away. I tried the suggested ?0000? and ?1234?, but neither worked. So keep in mind that you might need to go two sizes over what you normally wear, and if you have really big feet, these slippers probably dont come in a size for you at all :( As far as comfort, they are just fine - I really like the memory foam. i have had no complaint about clarity and have not been asked to repeat anything ive said so the mic works great.
