After reading the commentairesj'ai decided to purchase 43 when I made the 43 whatever the type of shoe (sport, city, roller skating, skiing etc ...) And guess what: amazing, they are just too much ... Shoes secu always great sizes so the shells does not interfere with the toes, in my case the size of the shoe for me, but my toes are a bit compressed by the shell, there is no game, not widen them and therefore to wear them during 8 hours of work. If these shoes are great, very slight but not convienent to all jobs: it is the S1, sneakers with a hull that's all. If you are a mason and as you walk on a plank with a top base will be crossed very easily. To book a salespeople, warehouse, forklift operators but not have people doing construction
