This is a 2-pack but so far for 6 months, Ive only needed one and have had no issues. Value for money doesn?t get any better. the softness and support these slippers have. - Sound quality exceeds my expectation. The only gripe I have is that I didnt get the instructions in the box so had to go online and download a manual which turned out not to be very informative. You get the softness with the support your head needs no caving, the pillow envelopes around your head neck and shoulders. Comprate per mio marito che ha il 43, abbiamo chiesto un cambio e preso il 44 perché risultavano troppo "precise" tendenti al piccolo, comunque molto soddisfatti I hope Merrell never quits making them. I do not really like using it for squatting; however, I did not have any issues with heavier weight putting pressure on my back when I tried it out. I will absolutely buy these again.
