Can new shoes affect HR so drastically?

Hi team.

Recently I got some new Asics Novablast 5's which I am loving so far. Previous to that I had a pair of shitty Nike Pegasus. The top 2 runs in the image are my first 2 runs with the new Asics - average HR of 159 and 142. The second 2 runs are my last 2 short runs in my Nikes - average HR of 173 and 177.

The runs were only separated by about 2 weeks, during which i did a half marathon in my Nikes at a 5.58km pace.

My question is, is something going wrong with my watches HR reader, or did the shoes really make that much of the difference?
