So had to rule those out. I can walk without looking like a new born giraffe learning to walk. These are great the only thing is I was hoping they were longer They?re just worn out at this point, so I bought these. After this I won?t recommend this product! i love reading reviews but i think some of the ladies were not being realistic. They also install very easily. PS: I worked in audio some time and know enough that this should not have been a problem. They work great and theyre compatible with my Android phone and computer. The 39 was definitely too small and could easily check that off my list.
