5-2yrs before they need to be replaced. I also use it to store the bike in the garage. I?ll probably put a pad at the ball of the foot. This Bluetooth speaker is pretty loud, yes as other reviewer said, its even louder than big speaker. Can?t express enough how much I love them! These are way smaller than normal size. A few adjustments and these pants would be perfect, but as is, they are mediocre at best. I have already thrown them away. Replaced an older model that wore out. it fits him well he is 5?9 around 190 pounds and a large extra large fit really good on him he said it did really good job of making you sweat.
