As I'm putting on my sneakers a year post purchase, I had to come back to right a review. I was developing tailor's bunions and always had achy feet. I went to a podiatrist who recommended inserts to support my high arches. Before purchasing the $60+ inserts there, I tried a few from Amazon and other stores. These were the immediate winner! Most others weren't "hard" like these so they did nothing to support my arch. I purchased 2 sets of these a year ago, one for my hiit workout sneakers and one for my outdoor, running/walking sneakers. I went up a half size in both sneakers as is often recommended for running, and also to accommodate the additional room the soles take up. Since then, the bunions are stable, no more distortion or bruising. And no foot aches/pain!

I will mention that they're not great for flats or shoes that are snug because they lift your feet a bit causing the ankle to slide out of a low-cut shoe, and as previously mentioned, they do take up a little bit of extra room in the shoe.

I did try the full-length as I was worried these wouldn't stay in place in the shoe, but much prefer these. They fit better imo and for the most part stay in place. I typically jam my foot into my sneaks quickly without untying and on rare occasion I'll have to reach in to minorly adjust them, but nbd.

These stay in place in my Vionic house shoes well. Also they're very good quality. They helped align my body wonderfully. Legs ankles, and helped with rounding and lifting my butt. As with high arches your butt doesn't change with age, it's your body's alignment.
That being said, unfortunately they are very stiff (maybe slightly too high)? This greatly hurt my circulation and caused a varicose vein and several spider veins to form on my legs after several different procedures to remove them.
I switch to Pro Foot that I had to glue into my Vionic house shoes. My home currently has slab/ laminate flooring. I have to have better house shoes as well as extra support
Through trial and error I now have comfy feet, no leg pain, corns not forming, and no new veins.

these are a good product, but didn't work for me

I put them in my shoes and right away my feet felt great. Only reason I gave four stars. Not a fan of the square stabilizers on the heel. Was an issue in a couple a pair of shoes.

I have a calcaneal spur, lots of pain at the bottom back of my right heal. I also have very high arches. These rigid insoles make a huge difference. I can go all day with them.

Things to know:
1. They are wide and do t fit into every show. Definitely won't fit in many feminine dress shoes.
2. They are uncomfortable in my cowboy boots with a 1" heel. I can imagine they would act similarly in any shoe with a heel.
3. They are rigid. You can feel the leading edge sometimes, but you get used to it and it hasn't caused me any problems yet.
4. Get a second pair - moving them from shoe to shoe is a pain.
5. The make Muck boots bearable.

I never bought inserts like this so I was a bit skeptical of the half length for the sole. I put them in and I was very pleased with the arch support. However, I don't know if it's my boots my feet or just the design of the support but on the left side I feel like I'm standing on the back of it with my heel. I can feel the edge. I'm thinking if it was just a quarter inch taller in the back with a little bit of slope away from your heel that it could be more comfortable. The right foot is not the same way. I think I wouldn't notice it at all if I didn't feel it on my left foot. I may try trimming some of it off.
