The product is quite nice, my shoe number is 45 and I bought Large size and it is tight.
Fantastic overshoes, true to size
Great item, great service as always cheers Merlin.
As my size 9 feet were at the upper end of Altura's sizing chart I worried about buying the Medium sized (black)overshoes, fearing they might be a bit 'neat'.
The overshoes turned out to be perfect on my Shimano RO77's giving ample stretch and have so far served me very well.
The reflective branding and rear zip ensure you're seen in the dark and they've kept the wind and rain out.
My only minor criticism is that I find them just a little bit loose around my shin/calf which may be down to my build rather than the overshoes.
Overall all though I'm ver happy with them and would buy them again.
