The Asics Gel Tactic has been around for years and is a personal favorite of mine. Asics updated the design in 2021. Big thanks to John for sending me some photos of the 2021 model, including some side-by-side comparisons with the 2019 model.
Here’s the back view of the 2021 models:
Here they are on the boxes:

Here’s a side view of the 2019 model (left) versus the 2021 model. The red arrow is pointing to a newly added plastic piece that seems to have been added for stability.
And lastly here’s a back view. The 2019 model is on the left. You can see the 2021 version comes up slightly higher at the last lace loop.
