You do have to tighten the straps very well or there will be vibration and noise from them. They were on sale as well, so I got them at a really good price. I am a happy camper with my new products. They fit very comfortably and they offer several increments of adjustment for bigger sizes heads, or to relieve more pressure. My daughter wears a 4 and usually they are just a wee bit big but these were super tight. I have several of their products and love them all. Saved Tons. Toe plug broke off in just a month of occasional wearing. very impressed! Prefer it over other brands as the cutouts are perfect.
