Glycerin GTS is the stability version of Brooks' Glycerin, which means it is the same shoe but with the added feature of GuideRails\u00ae to help guide the foot through regular pronation.\r\n\r\nGlycerin GTS is the most plush stability offering from Brooks, joining the Launch GTS<\/a> with its speed focus and Adrenaline GTS<\/a> which sits between the two in cushion.\r\n\r\nThis shoe retails at $160 USD, the same as last year and as the Transcend 4, 5, 6 and 7, the previous name for Brooks' most plush stability shoe (the cost was $10 lower for the first year when the name and design switched to \"Glycerin GTS 19\").\r\n\r\nThe listed weight remains at 10.5 oz. (297.7 g.) in a US M9 and drops slightly to 9.2 oz. (260.8 g.) in a US W7; the StealthFit version with a compression knit upper is about a half ounce lighter.\r\n\r\nBrooks allows runners to choose their preferences with choices for \u201cStealthFit\u201d or \u201cClassic\u201d for the upper and \u201cNeutral\u201d (Glycerin) or \u201cSupport\u201d (Glycering GTS) for the midsole, regular or wide width.\r\n\r\nGlycerin GTS competes with Saucony Omni<\/a>, New Balance Vongo<\/a>, and ASICS Gel-Kayano<\/a> for top-end stability offerings.\r\n\r\nOverall, I recommend Glycerin 21 GTS over the Saucony Omni 22 with two exceptions:\r\n\r\n1) I take the sock liner out of Omni to put in Glycerin; it's thicker and offers more arch support;\r\n\r\n2) You'll probably prefer Omni if you have a narrow foot. I stayed with the half-size smaller in Omni than Glycerin because though I'd prefer a slightly wider toe, the length was true to size. Sizing up would have made it really long. \r\n\r\nChoose Vongo if you want the extra stiffness and spring of a nylon-plated shoe and Glycerin GTS if your foot gets uncomfortable wearing a plated shoe. ","introduction_text":null,"conclusions":"[caption id=\"attachment_46448\" align=\"alignnone\" width=\"1280\"]\"Picture<\/span>[\/caption]\r\n\r\nThis is a remarkable shoe that is fun to run in<\/strong>. The main thing keeping me from giving it five stars is the \"meh\" sock liner. \r\n\r\nSock liner aside, try Glycerin GTS 21 for the best in cushion, stability, and upper support.\r\n\r\nBefore buying, first check to see if you have heavy wear patterns under the medial toe box on your previous shoes. \r\n\r\nThe new flex groove under Glycerin GTS's big toe exposes the midsole, and it might be a warning for you to try a different model to avoid premature wear.

True to the .2 oz drop in the listed weights (for women), the 21 in my size 10 weighed the same as last year's size 9.5.\r\n\r\nThe first run felt smooth, and this continued through my testing period (70 miles).","_first_impressions":"field_6313304ba000e","sole_unit":"[caption id=\"attachment_46452\" align=\"alignnone\" width=\"1280\"]\"Picture<\/span>[\/caption]\r\nThe midsole provides an excellent ride. Once again made of Brooks\u2019 nitrogen-infused DNA LOFT v3 material, it provides a softer landing than a traditional EVA blend and a lighter ride than the brand\u2019s DNA LOFT.\r\n\r\nThis nitrogen approach brings a unique feel: soft yet resilient \u2014 not plush, but comfortable<\/strong>. The ride is light and airy, with a rocker feel underfoot and quick transition into toe-off. The drop is 10 mm.\r\n\r\nThe GuideRails\u00ae remain largely unchanged since their 2019 revamp in Transcend 6. This unique approach to counter excess motion and alleviate pressure on knees and hips works together with the upper\u2019s heel counter to rein in movement. \r\n\r\nThe GuideRails\u00ae consist of the midsole extending up to border the shoe to provide support if needed. If not, they are not noticeable. The GuideRails\u00ae also help support the arch of the shoe to direct foot motion forward rather than rotating too far inward. \r\n\r\n[caption id=\"attachment_46446\" align=\"alignnone\" width=\"1280\"]\"Picture<\/span>[\/caption]\r\n\r\nAgain this year the thin, carbon-rubber outsole will be the first part of the shoe to evidence wear.
