Questions runners ask
- Is the Asics Gel-Nimbus or the Brooks Glycerin lighter?
- The Gel-Nimbus 28, by 0.7 oz in a men's US 9 (9.9 oz against 10.6 oz).
- Can I switch from the Asics Gel-Nimbus to the Brooks Glycerin?
- The drop matches at 8 mm, which is the spec that usually forces an adjustment, so most runners move across without one. Check the width and toebox instead.
- Which is more cushioned, the Asics Gel-Nimbus or the Brooks Glycerin?
- The Gel-Nimbus 28, on stack height: 43.5 mm under the heel against 38 mm. Stack is not the whole story, though; the foams differ too.
- Which costs more, the Asics Gel-Nimbus or the Brooks Glycerin?
- The Glycerin 23, by $10 at list ($165 against $175). That gap narrows once either one gets a successor.
