No, the air bubble will not burst easily. It's made out of really thick plastic. Other parts of the shoe will start falling apart before the bubble bursts with normal wear. I used to be a bit trainer obsessed and have an old favourite pair and the bubble did eventually burst but still perfectly wearable and no squeaking!
If you want comfort then you should go for New Balance. They may not look that great (apart from some of their collaborations which are immense) but they are seriously comfortable. The New Balance that are made in England are some of the highest quality trainers you can get.
