I got 4. They work but the velcro of the braces snags the sock part of these, which is unfortunate. My regular size is a 7M, however, in Yellow Box flip flops I normally buy an 8 for length. The whole container is small. However, it did “save my case” so-to-speak from any potential scratches and damage that might have otherwise been caused. Sí funciona para ensayar la guitarra conectada a un amplificador que tenga salida para audífonos (el adaptador es bastante útil) tanto por el largo del cable como por el rango de frecuencias. I replaced them with the Stanley version and they do SO much better! Love the appearance. They arrived today and the 44 is the same size as the 44 I tried on in the store. these things are very floppy.
