I recently recd this product on July of this year. Since my feet are skinny I think sizing up they would be too wide and not sucure on my feet. However, for more serious bike mechanics, best to splurge on a higher-end option. I finally went for this Sony model and have no reason to go elsewhere. Pros:- La calidad del sonido / Precio por el que pagaste-La potencia! keine feuchten Füße bekommen! I had an older version of these in black. and I still feel the soles somewhat. I have a slightly larger than average ear size for both women and men, at about 60-65 mm tall and I believe 35-40 mm wide. Only gave it a reduced rating because it is expensive as compared to the powdered spray or other products that provide similar relief.
