Its comfortable for short runs

Its comfortable for short runs, but anything over 5 and I get chaffing on the sides and back from the strap.  The bag is roomy but not stretchy so if I put my key and phone in there, they clink together when I run because there is no compression to stop them from doing so.  With no zipper, I fear losing my car key.  Too, the waist band is a little too big for me (5'1" 129 lbs).  It would be better if there was a belt loop to secure the extra band so it doesn't get caught on my shirt.

This vest is comfortable, but not snug or high-riding like I had hoped.  It is too lose for running, but it does conform well to the body so it feels almost naturally comfortable.  I do like the open mesh type material the vest is made of to help it breath while you sweat.  It seems to be pretty sturdy, and I like the price for a 'training' type vest.  When I can handle the weight consistantly and I get ready to run, I will look into something more suited to the movements.

Good shoes for lounging around or quick jogs on the weekend. I wouldn't recommend them for long runs. They're really comfortable, and the flex is great.

Its comfortable and secure but I don't have big arms, (about 14 inch) and if they were an inch smaller i don't know that it would fit. The description says it is adjustable to 11 inches but i would say for comfort so it doesnt move around when running probably more like 12 inches.

Good comfortable shoe, at least for short run. I've used them so far primarily on bike rides. The material is not leather, and though some have complained that the material doesn't breathe there are holes in the material and in the fabric portion too.

As Asics shoes, it is comfortable, The short-come is air flow not designed well, it is smelly after a busy day.

this is really made to be usefull and comfortable. running and neeling is like being in shorts but protected. If you want some action, this is what you need.

A bit uncomfortable, but for the price (and for a short 3 mile ride) it's great.

They are comfortable.  I haven't worn them very much yet, but they seem to have good support for running.

I was pleasantly surprised about how comfortable this was to run  in. It has plenty of room to stash all I need for my run and it doesnt ride up.

Overall, this armband works fine for me when I run.  I widened the key slot aperture a little to fit my keys and added a soft string lanyard to hold them in place.  However, the string is probably unnecessary; even with a widened aperture the key compartment feels pretty secure and I think it would hold my keys securely without the string.

Pros: The armband is comfortable and the screen is easy to access when the phone is inside.
Cons: It doesn't feel as secure as I'd like when I run, the phone side buttons can be a bit hard to access, and the slit in the back of the neoprene lets my sweat through into the phone compartment.  The key slot aperture was too narrow for my keys initially.

Pretty comfortable for short jogs but my knees hurt if I go more than 2-3 miles in these shoes.

I like the design simplicity of this shoe but don't use it for jogging or running as you will feel uncomfortable. I guess it is made for walking.

Comfortable fit. I like the sewn in cups. Not supportive enough for running though, maybe buy a smaller size

For the price, this is a great lightweight cushioned shoe for running or everyday wear. It runs a tad on the small side which might be contributing to my one gripe with it. The inside roof of the shoe is not flat so you feel the seam near the top of your toes where the shoes tongue meets the shoe. Other shoes I've had don't have this issue so maybe it'll get better as it breaks in. The slightly tighter fit for the size might be contributing to this as well. This is my first pair of K-Swiss shoes as I have been more of a New Balance, Nike, Addidas running shoe person. I can't comment on the durability of this yet so we'll see how it works out.

use as a running shoe. They are good for short distances.

These are cute, especially the camo print. The memory foam is lightweight and comfortable. I like that the toe box is roomy. The cons are that these aren't so breathable and the top of the heel where it meets your achilles rubs. If you were running with those short socks that don't show, then you may end up with blisters. For now, I'm wearing them for quick errands with the kids. I need to glue something back there so it doesn't rub because I refuse to wear higher socks. So just keep that in mind before you purchase.
