Great shoe!
Happy with the shoe so far--- very cushioned. It's nice because it comes in a wide size.

Very comfy
Overall I like the shoe. I love the glycerin shoes because they are very soft and have lots of cushion. I just wish they would have more color options and designs that they have for the ghost running shoe.

Comfortable but Heavy
The Gkycerin GTS 21 was a very comfortable shoe, lots of cushion and very stable, however it was a bit on the ‘heavier’ side. I prefer a lighter weight running shoe. But overall I would recommend this shoe for those who are looking for a stable shoe that has a lot of support.

Brooks women’s glycerine GTS
After consulting with a professional at Marathon sports I found out that these shoes are sustainability shoes and neutral shoes are a better fit for me for everyday use. So I have changed them for a neutral shoes but for 1-week try they had the best cushion support that I had seen.
