2015–16 season, Sokolík managed to recover from his injury and was featured in Yeovil Town's friendly matches. Since the start of the 2015–16 season, he quickly regained his first team place for the club, playing in the centre–back position. Sokolík scored his first goal for Yeovil Town, in a 2–2 draw against Dagenham & Redbridge on 10 October 2015. A month later on 7 November 2015, however, he received a red card in the 7th minute for an unprofessional foul, as the club won 1–0 against Maidstone United in the first round of the FA Cup. After serving a three match suspension, Sokolík returned to the starting line–up against Stevenage in the second round of the FA Cup and helped the club keep a clean in a 1–0 win on 5 December 2015. He then set up a goal for François Zoko to score Yeovil Town's only goal of the game, in a 1–1 draw against Portsmouth on 20 February 2016.

However, Sokolík soon lost his first team place due to competitions in Southend United's defence and was placed on the substitute bench once he returned from suspension. Despite this, Sokolík loan spell with the club was extended until 3 January 2015. However, Sokolík's loan spell with Southend United was soon cut after a knee injury kept him out for three months, which was later extended later in the 2014–15 season. By the time he departed from the club, Sokolík made two appearances in all competitions.
