Dependable - I'm very impressed with the overnight shipping and the kindness of your company. This shoe wears very well. My grandson is 6'4" and 200lbs and the shoe holds together for public use for a year and then is a great mowing shoe.

New Balance 645 - I ordered 4E width and in retrospect I think 2E would have sufficed. It is a little wide for my foot but very comfortable and looks great. It is not excessively wide but is a little spacey on the tip of the shoe. But all in all a nice shoe. I am pleased.

Zappos has done it again! First, kudos to Zappos.com! I have bought 5 pairs of shoes from here in the past 4 years, and for good reason. Great site layout, awesome selection, SUPER-fast shipping (I got this pair 3 days after I ordered them without paying a cent for shipping) and some of the best prices around. I'm definitely a Zappos.com shopper for life! As for these shoes…excellent! I needed a good pair of running shoes and New Balance has always worked best for me. I wear a men’s 15, which is a hard size to find. This pair fit just right with excellent cushioning. Feels like I'm running on pillows!

Order today; wear tomorrow - I agree with every one that wrote a review MR645 is the best tennis shoe I have had in 25 years light weight, fits great, and looks good definitely a five star shoe all round.

Great shoe... replace the insole to make it super! Excellent shoe. I bought green super feet insoles and it took it to a new level. I run pavement and these hold up nicely and the price is within the reasonable realm. It's a great neutral running shoe, so changing the insole may not be an issue. It is well built and no one has had anything negative to say about it visually. Get it.

Watch the heel width! I would caution you that if you have narrow heels, you might have a problem with this one. It feels a teeny bit loose on my heels, but not enough for me to worry about. I don't have extraordinarily narrow heels...if you do, you might have a problem with this shoe. They have great support and feel wonderful, but I'm not crazy about how they look. I have HUGE feet and am used to them not looking petite, but these shoes look a little extra clunky. A decent trade-off for something I can comfortably walk in, but it might be a bigger issue for some people. NBs are the only shoes that are wide enough for my feet. I hate buying men's shoes, but women's shoes simply don't fit me. If you have wide feet, NB owns the market, in my opinion.

Other shoes recommended by reviewer: Just about anything from New Balance!

Couldn't believe how light! I ordered these shoes for my husband because he hates to shop. I knew that he could try them on and send them back with no hassle or extra shipping costs. He loves the shoes and can't believe how lightweight they are and yet how much support he feels. He thinks I'm pretty smart. Thanks, Zappos, for making it so easy.

Fantastic Service - Lately it seems most companies have no idea what customer service means. So to my surprise, when my order was delivered the next day, I was elated. In addition, the follow up was excellent. Zappos is now the shoe store for me. Thank you.

Great surprise! I have been looking for comfortable work shoes for my husband, and not having much luck in a size 15. I came across this shoe and read the great reviews and decided to give them a shot. What a great choice. My husband describes these shoes like pillows on his feet. Thank you for all the previous comments that helped me with this purchase.

Great shoe but... They seem to run about a half size bigger. I normally take an 8.5 4E wide (even in NB) but I had to downsize to an 8 4E. Otherwise, this is a great shoe!

Comfortable - Comfortable, but felt a 1/2 size to small when I first got them. After breaking them in, they fell fine. I use them for the gym and running.

Good Spring - I run about 2-3 times per week and needed some more running shoes. I am a New Balance fan because they are one of the few companies that makes a sure that tends to be true to width for those like myself who have wide feet.

A 180 turn around! (yes its redundant) These shoes are amazing. I use to use a pricy pair of Asics but my feet ended up in a lot of pain. In fact it was a stress fracture that the shoes gave me. But these... AWESOME. Definitely a great shoe for the price.

MR645 - Zappos did it again. Ordered them late Sunday night, they were on my porch Monday night when I got home from work. Unbelievable service. As with other New Balance shoes I have, out of the box comfort and fit. Excellent all day comfort in the warehouse and workshop. Great for yard work. I wear them fishing and I am considering wearing them hunting in dry weather. Great for hiking also. I even have a pair for casual dress. With service like Zappos and comfort like New Balance why shop for shoes.

Perfect - These shoes are quite possibly the most comfortable pair of shoes I ever bought, not to mention that they look hot, too. I've always struggled shopping for shoes in the stores since I have to get a large size in extra wide. Usually, my choices are limited to five or so pairs in the store, none of which are particularly appealing. My last pair that I bought in the stores were deemed "grandpa shoes" by all of my friends. However, I was introduced to Zappos over the weekend, carrying a huge array of different styles in all sizes, even the uncommon ones. I placed my order on Friday night around midnight and my shoes arrived first thing Monday morning. I am so impressed with both Zappos quick service and the shoes themselves. I highly recommend you order them.

Good looking, decent shoe - This is a very nice looking shoe. I am a size 10 - this shoe felt a little too long. The shoe feels somewhere between good to average on other parameters. It doesn't have too much cushioning, but is otherwise light and comfortable. I personally didn't think this shoe had good arch support, but then my foot arch is quite profound. All in all, a decent shoe for the price.

Great Fit. Great Style. I always buy New Balance shoes because my feet never hurt when I wear them (unlike some other brands). I can never find shoes that fit my feet in stores (well, I can usually get just some black run of the mill New Balance shoes), but Zappos got me the exact size I wanted and they fit perfectly. On a side note... Zappos is just plain awesome! I opted for the free shipping and ordered fairly late in the day, but an hour or two later, I got an e-mail saying they had upgraded my shipping free of charge! I thought to myself that they must have gone to priority mail or something cheap, but it turns out they bumped me from the free 4-5 day shipping option to next day air saver!
