These cushions are MASSIVE, both in the thickness of the foam and in the diameter of the ear holes. I have been wearing Nike Celso basic thong sandals for about 15 years or more. They run half inch short in length. They were not properly stitched on the side, I?m very disappointed. They do look better than the more expensive Birkenstock (definitely too casual, expensive, and mostly sandal-like anyway) and Ive never tried on a Birkenstock that felt any better on first fit than these do. For the price you pay, this is a great pull up and dip stand. The bearings/spacers inside the wheel do not hold up. Would I purchase again? So far, yes. Says it works with a iPhone 12 and it does NOT, it wouldn?t even work with my 10! Reception of weak signals is amazing .
