Purchased size 6.5, normally wears 6 in regular shoes, like Vans or ballet flats. Training for a full marathon - These shoes are very light weight and have good cushion for someone who has a low arch. After running in them about 3-4 times, 4-6 miles each time, I would say that the toe box is still snug compared to the original Glycerin 20s. I would also recommend wearing an ankle sock or crew sock since the sock-like shoe rubs a little bit when wearing no-show socks. Overall, I still plan to train in these shoes since the marathon will be in October and the light colors will attract less heat than a dark color. I will also be adding a custom insole when I begin higher mileage runs. Overall, still recommend for the look and similar feel to the original 20s.

I received a voucher for brooks which I then purchased the Glycerin StealthFit 20. To my surprise this shoe literally feels weightless, like walking on a cloud. Other shoe brands market the “foam/soft sole” but you can feel the ground you walk on when wearing those “other” brands. Being my first ever brooks shoes I’m blown away with how much support and comfort they offer me! Im new to running and I can wear my brooks after my workout where as in the past with other brands I’d be kicking them off before I left the gym. These are AMAZING

Absolutely in love with these shoes! I bought these to replace my old running shoes, and while I definitely needed to break them in a little, I couldn't be happier with how they have performed. There is a decent amount of cushion, while still maintaining their responsiveness. The sock like fit is extremely comfortable, and wearing them feels like walking on a cloud. Not to mention they are incredibly stylish! I intended to keep these just for running, but I love wearing them so much they have become a regular work shoe for me as well!
