The Brooks Glycerin 20 is less expensive than it used to be and is absolutely worth the $100. Lasts 500+ miles, perfect for easy and long runs

Overall

This was my 4th pair of glycerins and the only ones I didn’t love. Not the same level of cushioning as the others. The placing system and laces puts too much pressure on the top of the foot. Would not recommend.

Comfortable and durable.  I have had 3 pairs of these shoes that I used for half-marathon and base training over the past year, and had no issues with injuries.

Overall

Great running shoe- not springy and probably not huge on energy return- or the lightest shoe -but comfortable km after km and good for whatever your training program throws at you from fast intervals to easy long runs. Fits true to size and very durable.
