In everything very good product
Just the existing sole needs to be removed and this one needs to be put in..
The shoe should be a little comfortable because it is a little thicker than the usual plain soles.
Perfect in stepping.

Unfortunately, they are very thick and do not fit well inside the shoe. The size 43 that I bought was much larger than my size 43 shoes. I also have reservations about whether they are actually memory foam because after several hours of use, they have not been compressed at all in the areas where they should have been.

The insoles are very thick. In terms of orthostasis, I give them an excellent rating. On June 13, 2023, I ordered another 4 pairs and put them in all my shoes. Very good and cheap

So... here we go.
The insoles are very thick, resulting in my case, when I put them in boots, my toes hit the front. I would buy them again only if the shoes are one size larger than normal.
(That is, if you wear size 45 and you receive shoes size 46 as a gift, definitely using these insoles will be fine for you.)

Quite good and soft insoles. They are a bit thick though, which is logical. I wear size 44 and I put them in my sports shoes (Asics Nimbus 24) and they fit perfectly. I just had to remove the insoles that were already in the shoes. With thin socks, the foot fits in, although it gets a little warm because the space inside is reduced. With thick socks, it will be a bit more difficult for the foot

Thick sole and I was scared to fit it but in the end it makes sense because it fits perfectly on my foot. Just what I need for sports

For almost a month, it hasn't worn out at all. On weekdays, I take over 15,000 steps and on weekends at least 30,000 steps a day. In terms of posture, I give it an excellent rating for the 12-hour period, you don't feel anything with ultraboost. Perfect combination.
