Advice for Road Runners: The Brooks Men's Glycerin GTS 21 Road Running Shoes provide added stability and premium cushioning.
For the avoidance of doubt, GTS stands for 'go-to-support'. These are the stability version of the Brooks Glycerin.
The Glycerin GTS 21's midsole consists of Brooks' DNA LOFT v3 cushioning. This nitrogen-infused foam provides lots of plush cushioning.
If you wore the Glycerin GTS 20, please note that the Glycerin GTS 21's midsole has an extra 2 mm of DNA LOFT v3 cushioning.
The added stability provided by the Glycerin GTS 21 stems from Brooks' GuideRails™. This support system works in a similar way to the bumpers at a bowling alley; they support your body's natural motion path while keeping excess motion in check.
A new RoadTack rubber on the outsole creates lightweight and durable cushioning.
The new, engineered warp knit upper is breathable and it provides support in vital areas across the foot.
The Brooks Men's Glycerin GTS 21 Road Running Shoes are best matched to slow and steady paced training runs. As they provide significant levels of cushioning, they should be very comfortable on long runs. As a reminder, please note that these are the stability version of the Brooks Glycerin.
Take your Brooks gear for a 90-day trial run. Put it through its paces and sweat in it as much as you want. If you are not 100% satisfied, return it to us for free.
Shoe size is a personal preference and everyone's feet are different, but we want to ensure you avoid any pain or discomfort from bruised toenails, rubbing, blistering or pins and needles.
Your running shoes should have enough width to allow you to spread your toes and should have some space at the front (we recommend having a half to one thumb's width of space from the end of your longest toe to the front of your running shoes).
This usually means that your running shoe will be at least a half size bigger than your regular shoe size though this can vary from brand to brand.
