These are true to size and size 11's were a perfect fit for me. While not as lightweight as other running shoes, they're not heavy either, and of great importance, they're extremely comfortable. This is the 4th pair of shoes I've purchased over the past 6 months and the best by far. The others were Adidas and while the shoes look good, you can tell they're cheaply made. Sadly, this seems to be the trend, but I'm delighted these Nike Lunar Caldra shoes are well constructed. I'm of the impression they'll stand the test of time (and I'll return to update this if they don't).While not a fan of red/bright colors, aside from University of Louisville game wear (Go CARDS!), I purchased the University Red/White/Ttl Crmsn color shoes and they look great. The other shoe design/colors look slick, might just have to grab a pair of the blue.I like the shoes so much that in addition to running, they've become my "go-to" shoes whenever I run errands, go grocery shopping, etc., because they're so comfortable.Shoe looks nice and is pretty comfortable, however the tongue has a sharp edge at the top that digs in to your ankle. I had to cut the top off the tongue off to be able to wear them. I’m worried the tongue is going to fray since I had to cut down about a 1/2 to 3/4 of an inch.Possibly the most comfortable pair of shoes I've ever worn on day one. You can't ask for more out of a foot rubber sling device for the money. This is peak technology in shoething.the tongue is a bit rough - I need to wear higher socks to prevent rubbing against the joint between my foot & my leg.These shoes are the greatest thing mankind has ever made for running, they are really lightweight and it's cushioning is pretty much perfect. only problem is it is quite smaller, I recommend buy it 1 or 2 sizes larger for it to fit well.While the design is nice, the material used is a very this mesh like material. After a few months there was already a hole worn in the toe area.Very comfy but way too small for the size. I own other Nike sneakers at the same size and these I can't even lace them up after I force my feet in. If the size is correct I don't see how the laces wouldn't even be long enough. Something is off with these. Really liked them too but can't force fit something that size is screwed up like that.Looks wonderful, but fabric is a bit rough and shoe feels far from an 11 which I wear in other Nikesbest trainers everYes it ran small.....i always order size which fit to me..... But in its case the shoes seems to be small in size.... Don't the reason
