It gets wrapped up slowly over time. Size was perfect great slide and confertable I have to first preface this with that Im a very big fan of Sennheiser products. UPDATE 2/3/15 - These slippers have a 1 year warranty - went to Bearpaws web page and filed a warranty form. Tiene 3 botones para pausar/reanudar la música con un toque en el botón central (Con dos y tres toques cambias de pista), y los otros botones para subir o bajar la música. I love these so much, the material on the toe does wear down with walking outside but theyre so cute. I used it for 5 days for about 1- 2 hours with 30-40mins of it for cardio. He visto otros portabultos que traen hasta 4 tornillos, lo que distribuye la presión y hace que el protabultos sea mas estable. UPDATE: Because I purchased a 24" Midwest Deluxe Bolster Pet Bed and about 6 weeks later purchased a 22" Midwest Deluxe Bolster Pet Bed, Amazon only allowed me ONE REVIEW. I would highly recommend them.
