MeshPro Original Aeration Insoles (Hard) from Japan

These are the first insoles that help keep your feet dry. Because of the way they are constructed, each step moves air. They keep your feet harder for rucking, and other activities. Make sure you put the grip side down. And you can remove and install them easily. Quality construction lasted longer than the shoe I put it in. Great product.

Air gaps are what keeps your feet warm. This is the only product I know that actually allows this. Other insoles with a fine mesh and thick foam insert just absorb moisture so not only do your feet and socks get damp and sweat, so do you insoles. This not only make my feet feel damp and hot, but it also sticks up my boots.With these, I feet stay warm and only the socks get damp from sweating. When I change out my socks, they don't soak up the moisture from the insole because there's very little to begin with.I wish I can get more stateside but it seems like these and the soft version are sold out.

Bought for use while working in warehouse, helps shoes stay in place as they are springy. Was hoping that this would prevent my need for spraying deodorant on my feet but this doesn't keep up to how bad my feet sweat, still helps but plastic grid is a plastic grid and will leave marks on feet.

When I first reviewed these, I thought they were awesome because of cooling down my feet. However, after using them for just a little while, they started to build up lint from my socks. It was so awful, I just threw them away...

My feet have always sweated badly, no matter what socks I wear, but these make a huge difference because they allow ventilation under your feet, yet are still very comfortable. The soft versions work, but not as well, & they don't last nearly as long. I replace the hard version roughly every 3 months, usually because they get clogged with lint & stop ventilating as well. I definitely recommend trying them for sweaty feet...

They felt like firm cushions at first, kept my feet cooler and dryer. They collapsed after a few days and then felt like stepping on uncomfortable hard grids.

These are nice - really help with keeping feet try and adding some cush. I find myself putting a light leather or other breathable insole over the top, to avoid feeling like I'm standing on coarse mesh.

Air gets to the entire foot. No odor ! Massages the feet with every step.
