Best Bargain Review - New Balance Men's Mx623 Training Shoe

I purchased the grey, which actually has a suede upper rather than leather. I've worn the 621 and 622 and liked them both. While still a decent shoe, the 623 is not as good. Here's what I don't like compared to the other models: the suede upper does not give as much lateral support - in fact, I have to keep tightening the shoe strings throughout my workout; the shoe runs a little larger than the other models; but most of all, the forefront cushioning is not very good at all. Now, I use my shoes for working out and cross-training, so if you just want a walking/work shoe, this should be fine; just doesn't do that well with heavy pounding. If you get the 623 for exercise, opt for the one with a leather upper - probably better. However, one plus for the suede is that it is cooler and more breathable than the leather, so if you wear all day, something to consider.
