Very comfortable & feel much sturdier than many of the simple (which these are) flip flops out there. Choose this as it had the options of red and fog lights so can be used dismounted at night (retaining night vision when needed). I wore them every day all day for about a week including a 6-mile hike. if this is too much $$$, look at the Doss, UE Megablast and Charge4. The new size 9-10 fit her perfectly. Crystal clear treble and mids (Ive seen other products with reviews saying the mids were muddy or distorted). I was initially skeptical about ordering these through Amazon and not Nordstrom because of a potential return and not sure if they are knock-offs. The sound, the BASS that comes out of this speaker? Its defying! The people in those images must be very thin. Actually increased my weights by 20 lbs by just using this better pad.
