i sometimes get a wide shoe,simply so i have some wiggle room for my toes.sometimes beacause of the cut of the shoe.
but i ordered my first pair of cycling shoes off of ebay and,they are plenty wide at the toe.
they are diadora elite 2000s and,i only paid like $25 for them and,they are plenty wide,even with thick white socks on. however i had no idea that the sole was so slippery and,when trying them on i just about did a 360 somersault. why must the sole be so slippery.
ANYWAY,i dont actually see a width in the shoe or on the box.but the toebox is pretty wide,but i dont know if they are 5e wide.hope this helps.
