Hi I am in a situation where I don't own any higher quality shoes yet so I don't know how various lasts fit me for comparison. I am normally a size 12US. It seems that a lot of shoe makers with recommend either 11UK or 11.5UK depending on the last. I was trying to decide between these two shoes(one meermin and one carmina): http://www.shop.carminashoemaker.com/articulo.asp?idarticulo=5387056 http://www.meermin.es/ficha_articulo.php?id=1967 I was recommended I get an 11.5UK in the Meermin New Ray last by them (I guess it is narrower in the toe). So my question is what are others experience on here with the INCA last from Carmina? If you are consistently a 12US in tennis shoes/other popular shoe companies etc what worked for you on the INCA? Thanks for your help.
