En la app puedes cambiar los comandos de voz a Español! I hate writing a bad review, yet amazon is not allowing for a return or exchange of this item and it looks like I am left with a defective product. And heres the rub. Easy to assemble if you are following the instructions exactly. Have to send back. They were his favorite among all other sdidas options. BUT they tend to get me through the cooler/cold months before I have to replace them, which is better than most slippers you wear a lot in winter. Super comfortable for a two year old! Size was a 7 but its more of a 6 1/2. This adapter supports the Thunderbolt which is a perfect fit for my needs.
