Airplane Travel Footrest (11.2x8.3”), Premium Foot Hammock to Relax Feet During Long Flights, Office Desk Foot Rest, Comfortable w/Soft Memory Foam, Essential Accessory for Plane Journey

They look and feel good but can really rate them.

This Cozlow Airplane Travel Footrest (11.2x8.3”), Premium Foot Hammock to Relax Feet is a nice compact foot hammock to toss in your carry on. It isn't as bulky as the ones with the hard board in the middle which is both a benefit and a negative. The lack of hard foot board means it is lighter and packs up small, but it does mean your feet are more like in hammocks than on a floating platform when you're using it.

The Airplane Travel Footrest is a decent travel accessory, and the memory foam adds comfort for long flights. It helps relieve some leg strain, but adjusting it for the perfect height can be tricky. Overall, it's useful but not a game-changer.
