THE SHORT ANSWER
Drop is the real difference: 6 mm on the Guide 19 against 10 mm on the Structure 26. Coming off the Structure 26, the Guide 19 loads your calves and Achilles harder for the first couple of weeks. Both sit in the same role (stability). The Guide 19 lists $5 lower.

Questions runners ask
- Is the Nike Structure or the Saucony Guide lighter?
- The Guide 19, by 0.7 oz in a men's US 9 (9.7 oz against 10.4 oz).
- Can I switch from the Nike Structure to the Saucony Guide?
- Yes, but ease into it. The drop moves 4 mm (10 mm on the Structure 26, 6 mm on the Guide 19), which changes where your foot loads at landing. Give it two weeks of easy running before a hard session.
- Which is more cushioned, the Nike Structure or the Saucony Guide?
- The Structure 26, on stack height: 38 mm under the heel against 35 mm. Stack is not the whole story, though; the foams differ too.
- Which costs more, the Nike Structure or the Saucony Guide?
- The Structure 26, by $5 at list ($145 against $140). That gap narrows once either one gets a successor.
