Don't drop $200+ on the 990v6 just because they're trendy right now. That said, they're actually solid shoes if you need the support, but for casual walking and light jogging a few times a week, you're honestly overpaying for what you're using them for. The 990v6 is built for people who either need serious stability (they've got a reputation for that) or are willing to pay for the heritage/brand factor. If you're doing maybe three jogs a week and mostly casual stuff, a mid-range shoe from New Balance, ASICS, or even Saucony in the $100-130 range would handle that workload just fine.
The real question is whether you need the stability features the 990v6 is known for. I spend a lot of time on my feet at work and know how much the right shoe matters, but that's different from what you're describing. If your feet feel fine in other shoes and you're not dealing with overpronation or pain, cheaper options will work. Look at what features actually matter to you - cushioning, arch support, breathability - and match those in a lower price point instead of paying extra for a name. Try on a few pairs in the $100-130 range and see how they feel. Honestly if they're comfortable and durable, your body won't know the difference between those and the 990v6s after a few weeks of use.
