These mesh "training" shoes are very light weight and flexible. There's a bit of cushioning but not much arch support in the traditional sense. While they are mesh and designed to be worn without socks, my feet got hot after just walking about inside my house for a test wearing. Considering the brand and price, I expected more-- these border on cheaply made. The fit is a bit short; my toes touched the box end of my usual size 7. They remind me of wrestling shoes (better for working out indoors vs. walking/running on hard surfaces). I'm looking for something comfortable for walking (upcoming vacation) that could also be used for casual bike riding. I currently own an old pair of very structured/thick soled New Balance running shoes, which are lousy for bike riding because I can't feel the pedals (no feedback). They are supportive for walking but unattractive. I also wear an old pair of Vans suede skate sneakers... both my NB and Vans need replacing, and I was hoping to kill two birds with one shoe (i.e., a cute shoe for walking around Sea World all day and riding my 3 y/o son to the park on my bike).
