I have these and recommend them. I've had them for around 5 months and they are well cushioned and have lasted about 5 months with not much damage.
Been using this for my sneakers. It really works! Fine mist and dries quickly. Keeps white sneakers looking new much longer.

I've posted it a couple times, but it doesn't look like it's coming through. Trying on desktop.

The 21 and 22 typically have a snug fit because they are designed for running. Joggers tend to prefer a snug fit so they don’t slide around.
They will break in and widen out a bit, took mind about a month. If they are really tight you can do like me and take out the insole,you'll be in direct contact with the boost which is squishy and comfortable, the insole is not really needed in UN
Next time, go half or full size up on 21 and 22, if you want the extra space and insole, but I find the extra length looks wierd when I go bigger.
The DNA 1.0 to 5.0 are a bit wider, and are designed for everyday use (not just running). Personally I go TTS on the DNA and take out the insoles to give me more vertical space.
One tip: I have a shoe spacer to help break-in some sneakers, it's worth the $15-20 to save the pain of breaking in a pair of sneakers. I bought only one (not the pair) an every few days swap them from left to right until they've stretched out. The extra nodes allow you to stretch different parts of the show and the handle has an inner and outer screw which widens and lengthens the stretcher. It's old tech,, but good tech 😁
Since it is slightly opaque you don't want to paint it, you just want to remove the oxidation.

You have to pay for the service. But I heard good things from them
You would mix the solution with water, with about 4-6 squirts per pair, so yeah you would have enough leftover for another 3

In regards to the rubbing, neither my wife nor I have had any rubbing issues as this was a big problem for her in general pre-UB’s. All I can think of is to just wear thicker socks like you’re doing, or maybe look into silicone gel toe caps for when you wear thinner socks.
