I just recieved a pair of Nike Eldoret II through the post, and I'm contemplating returning them. They fit perfectly in terms of width, both in the heel & forefoot. However, theres about 1/2 an inch of extra toebox space forward of my middle three tows (i.e. not the big or little ones). Is it unrealistic to expect spikes to fit any better than this? Will the extra room make them un-usable for me? Its the first pair of 'proper' track spikes I've invested in & I dont want to make a mistake...
