“i found the 12’s. WAY too hard.”— @neilhulme8426 on YouTube
“I went with the same size as my boston 12 for the 13, and had to return them due to how small they ran.”— @kev60625 on YouTube
“not having laces that stick in place isn't acceptable”— @Secretlyanothername on YouTube
“al estrechar las hormas, ninguna”— @fordaok on YouTube
“I never got along with B12. They just don't work for heel strikers”— @justoutlaw6423 on YouTube
“Me gusta más la 12 por el lightstrike 2.0 en medio pie, favoreciendo la duración”— @davidbetan602 on YouTube
“no entiendo por qué una Boston 13 tiene todavía una capa de Lightstrike común, que es un material bastante duro y que devuelve poco.”— @cristianfcao on YouTube
“Lo del collar del talón era lo peor de la Boston 12”— @JOTIXOXO on YouTube
“Son como correr con una plantilla de madera. Malísimo me lesionaron el tendón.”— @marianonecochea3856 on YouTube
“En la 12 se aflojan cada 2x3”— @thiagobritoramirez9837 on YouTube
“el collar de la 11 me destrozaba el aquiles hasta el punto de hacerme heridas”— @Suarez-ce5xx on YouTube
“creo que el concepto del modelo Boston murio en ese cambio que hizo adidas”— @rodrigogorosito4206 on YouTube
Not complaints — practical notes from owners that didn't affect the score.
“I made this mistake went half down in the 13s as I did that in the 12s and they were too short. Think the extra padding at the back has swallowed up the half size.”— Leej-xxx on Reddit
“I will take my Bostons out for a 15+ mile run but will not take the EVO for more than 10. Bostons are a marathon training shoe the EVO is not”— NewCPVI on Reddit
“if I did size up the shoes would end up too long and cause other issues. I wear the Evo SL in the same size they fit perfect.”— highdon on Reddit
“they have energy rods in them making them a bit stiffer than what you'd probably want for a casual walking shoe.”— Ok-Supermarket4085 on Reddit
“Comfort isn't the aim of this shoe. The mix of LSP and a firmer Light strike 'carrier' foam under the heel signals it's a daily trainer. The rods signal it can/should be used for faster speedwork. It's not a heavily cushioned long run slow cruiser for sure.”— Virtual_Opinion_8630 on Reddit
“They feel like they might be a tad more narrow and just a bit shorter, but the same size works for me”— Much_Basis_6965 on Reddit
“Fast day or long run daily trainer, yes. Not recommended when you want to go slow (but you can still)”— canocka on Reddit
“It's important to note that the midsole on the B13 is quite similar to that of the B12. The forefoot also has LS 2.0, you can see it on the medial side of the shoe.”— atwoz123 on Reddit
