I was concerned after reading a number of bad reviews about New Balance and this model (MX623). As far as size, I agree with other reviews and would say this shoe is about 1/2" too small with a slightly narrow toe box. Arch support is minimal in my opinion but I use aftermarket New Balance Sport Cushion insoles that have a plastic polycarbon arch.

People also mentioned the shoe is made in Vietnam but I just received an all-black pair that was made in China.  Did New Balance change factories? Either way, I'm not happy they aren't made in the USA like my 1 year old New Balance MR1226 running shoes. New Balance was the last major athletic show company to make shoes in the U.S.
