We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I've worn out my almost-daily gym sneakers. I use them for weights, cardio, everything, but the bottoms have gotten slippery and the insides are disintegrating. No surprise but I hate to give up on shoes I like.
I do have a pair of "running" shoes but I don't really run much these days. Stair machine is fine cardio if you go fast enough.
First World problems, right? I like Sperry Topsider sneakers on the boat. Good grip on a wet boat.
Only New Balance for me, cuz they make narrow sizes.
What exactly is cross-training? It's not what I do, because I do not have a primary sport any more due to injuries.
What do our gym rat readers like for mixed workouts?
I use Merrell Vapor Glove (minimalist shoe) for both my daily 4 mile run and at the gym lifting weights. I get over 700 miles on them before they need to be replaced. It just takes time to switch over from padded running shoes to "barefoot" style.
I just got a new pair of RedWings pull-ons, first new pair in over 10 years. They have a great machine that precisely measures size/width for each foot, and then you walk over it a few times so it can measure which insoles you should use (measures impact: force, outline and arch). My wife came along and got a pair, too, and she's still going on about how comfortable they are.
I didn't know that RedWing bought up Vasque a few years ago - so now they do hiking boots, too.
For trainers/running: If you find a pair you like, buy an identical new pair, pronto, and put'em in the closet. I try to do this with everything.
Shoes have been an issue for me all my life. So when I buy a pair of shoes/sneakers/boots that are great and really work for me I immediately go buy a second pair. My experience is that cost and "name" don't mean squat when it comes to fitting "your/my" foot well. I walk/hike so I do wear out the shoes and this means if they are a problem I know it. I'm not just wearing them to dinner or walking a little in a gym. My current technique for buying good shoes is simple: I buy my shoes at Big 5, I buy sales only, typically $19 and I wear them for a week, on hikes, walking around. If they don't fit well, give me problems in any way I give them to Goodwill. If they fit well and give me no problems I wear them until they fall apart. I intentionally have 2-4 pair that I know fit me and I could wear anywhere. Because I now live in the South West I mostly wear sandals all the time but I wear shoes/sneakers to hike.
You said, "Only New Balance for me, cuz they make narrow sizes." I find that funny because with size 8-1/2 EEE feet the New Balance "wide" fit really well.
For other brands I end up with a size 9 EE, which is both too long and not wide enough.
